There was no satellite recording today because N was still troubleshooting the prototype ground station, so a bending of time, this recording is from tomorrow, the day of my operation. As I write this, I am waiting for the 'big day'. It’s raining, I can hear but not see the water cascade onto the hard facade the 1970s hospital building as the long curtains in my room are closed. Possibly for privacy or, I speculate, because the my roommate left for the operating theatre this morning when it was still dark. Either way the yellow glow of the artificial lights makes me groggy before anyone has even laid a finger on my body. A nurse searches for the word in English, “I will tie the bandage tight so as to stop a …. hema-toma." "Your vein opened too wide," she explains. "God", I say, "that sounds bad!" She reassures me, then sticks a cannula above my wrist where there seems too little flesh between skin and bone to cushion its intrusion. It stings. I watch my blood back flow into the two plastic tiny tubes. “I think that I’m going to throw up,” I say as a nurse announces lunch. I am given a cardboard bowl to throw up in and a tray with a clear soup, asparagus, rice, lettuce leaves, and a yogurt. I skip the yogurt and throwing up, and decide that I need sunlight. Opening the long curtains brings into view a drab but solid looking Altbau opposite. The rest of the day passes with time suspended between boredom, anxiety and grief, the sources of which I guess but chose not to give shape to with words. Satellite not known.

I am on holiday with my sister, Ray, and her partner Ben. When we check into our Airbnb the host, a women a little younger than our mother, apologies for our "bad luck" with the wet weather. We engage in pleasantries about how unpredictable the summer has been, and wet and warm the spring was. "We are not looking after Mother Earth", our host concludes. Her tone is serious. I think I detect fear, but cannot be sure. We say that "we do not mind", that "we will swim anyway", because "we are from the North".

There were flood risks in Southern California over the last few days as the region received storm cell bursts. I recorded my image during a clear break in the rain, though the air, ground, trees and sidewalks were still soggy. A woman was throwing a branch to her Australian Shepherd in the park while I was recording the image. The dog was kicking up so much mud its multicoloured fur was completely mud-coloured after a few minutes. As I returned inside after the satellite pass, another burst of rain began pounding the roof of my Mom's condo.

Today the light is a pale yellow and the air shimmers with leftover water evaporating from puddles and storm drains in LA. The city smells more intensely, as if all the materials on concrete surfaces, roads and sprawling buildings have sublimated. Throughout the satellite pass, the roar of airplanes taking off from runways at nearby LAX was palpable, though the misty clouds meant none of the planes could be seen.

The sun was very bright and the air so warm today, I ended up in a t-shirt while capturing the satellite pass. The park was lively as a soccer team started warming up and a group of walking womxn did laps on the sand trail. I was on a video call during the whole satellite pass, and this made me reflect on the ways the signal from my phone was relaying through a nearby cell tower and onward to the other side of the planet, while the NOAA satellite above me sent radio waves to the ground – I wondered, did the signals touch?

The humidity is unusually high today- around 88% The local park was very vibrant and active, with a young soccer team and a group of people throwing frisbees. On my way back home I noticed several policemen checking parked cars along Green Valley Circle. One group had what looked like a kit with a brush- I wondered if this was for fingerprints. Had the humidity of the air affected which fingerprints could be lifted off car doors, handles and windows?

The air has been warm but the visibility is low- a light fog has settled over the Los Angeles basin. Throughout the day the fog became more dense, and was likely trapped by the marine layer of cold air coming in from the Pacific.

On my way to LAX airport to drop off my brother this morning, the air was so misty and wet, and the rain was so "strong", that people were driving at almost half the normal speed limit- a sign that the rain is affecting how people feel in LA. I didn't think the same would be true of people or drivers in the Pacific Northwest or Europe. By the time I caught the satellite pass, the clouds had parted and the sun was hot on the balcony.

I was on a palm tree-lined neighbourhood street in Culver City, around the corner from the Diorama-Museum of Bhagavad-gita, where I had booked a tour for the morning of January 1st. I balanced my laptop on the hood of my brother's car and held the antenna to the clear blue sky. The weather was bucolic, as if even the light had slowed down.

A storm has passed through southern California overnight, and there are still impressive clouds in the sky. The air is brisk and full of water. I captured an image from NOAA-15 which turned out without glitches but unusually dark – as if the satellite was somehow sensing the atmosphere on the ground.

A pack of coyotes howled in the distance as I captured this satellite image. I was on the edge of Yucca Valley bordering Joshua Tree National Park, and while the air was cold, the sun was very strong, reaching into the crevices of the hills and boulders. The wind whistled among the Joshua Trees and Cholla Cacti. I felt very 'close' to the satellite too- there was so little radio noise, the moment I picked up my antenna, the satellite signal came through clearly, even though it had barely crested the northern horizon. I didn't need to look at the compass on my phone because the north star had shone so brightly the previous evening and it was easy to remember where 'north' was.

Standing in an elevated parking lot attached to the Heather Village condominium complex in Culver City, Los Angeles, I could hear engines starting and wheels tentatively moving as commuters started their day. The nearby 405 Freeway made a constant whoosh-hum, and airplanes took off and landed at LAX.

From the 'point on the bluffs' in Pacific Palisades, Los Angeles, I could see as far as Palos Verdes and Catalina Island. It was a bright, warm day, and many people were out walking. The satellite 'set' over the Pacific Ocean- I felt I could hear it for much longer than I normally can from a place in the city, as there was only air between me and the horizon.

I made a poor choice not to bring a hat and gloves when I went out for the pass today, as Hackney Downs was sunny but extremely cold and windy. Even the dogs running in the park had sweaters and multicoloured outfits on. A man stopped and asked what I was doing, and a woman and a dog happily took some photos of me.

I wanted to catch the satellite pass in my back garden, but the gate was so cold the lock had frozen or stuck, and I couldn't open it. I hurried to Hackney Downs and found a spot very close to the entrance in the long shadows of the plane trees. As I was listening to the satellite a woman with bright pink gloves came up behind me and asked what I was doing. When I told her about the satellite and my radio antenna, she immediately asked – are you a creative? This is the second time a person in Hackney Downs has asked me whether I am a 'creative' while I am holding my antenna. She kindly took the photo I uploaded.

I assembled my antenna on a bench in a dim pool of lamplight after sunset in the local park. I had just come back from the march for Palestine and still had my placard with me. As I was already so cold and tired from being out at the march all day, and the park was even colder than the streets, I struggled to concentrate, almost dropping my antenna and laptop.

I stayed almost entirely inside during this satellite pass, in sweatpants, slippers and an oversized jumper I had found in a vintage store in Buenos Aires. Even before I stuck my arm outside the kitchen window to catch the last half of the satellite pass, the antenna was picking up NOAA-18 inside the flat. This made me wonder about the porousness of our flat to the 'weather' of radio. Nicola took a look at my satellite image, he pointed out a cluster of white pixels where Mt Etna should be: the volcano is snow covered!

Half of Clapton Pond was frozen on the surface, the other half (receiving the sun over the tops of buildings) was not. Pigeons stayed out of the shade, milling about the edge of the pond and periodically bursting into the sky.

The weather today is gorgeous – bright blue skies and golden sunlight. All morning the DJs on NTS radio have been remarking on the beautiful (if cold) weather conditions. To soak up the weather as much as I could, I found a spot in the middle of the widest field in Hackney Downs and set up my ground station. I was exposed in other ways too- many people stared and pointed at me from a distance, but none came near.

The weather was bright and gusty, and bitingly cold. Hackney Downs was wide open and clear, so clear it made me wonder what it was before there was London. There were so many dogs being walked in Hackney Downs – I saw one person holding eight dogs – and a short-haired Australian Shepherd ran up to my laptop during the satellite pass. I stopped to pet her, and I wondered if her energy was having an influence on the satellite image.

I was in between two meetings on Microsoft Teams – one finishing and another one starting at 11:30. NOAA-18 was due to start its orbit over London at 11:31. I wondered – was there time for the weather? I tried to 'create time' by writing a 'I'm five minutes late' message to the person I was due to meet, and took my laptop to the bedroom to the nearest possible window to receive the satellite pass. As I was counting the minutes of the pass I was also counting how late I would be. I wished I could stay in the 'weather' of the bedroom and sunny back garden, and avoid the 'weather' of the Teams meeting room!

It was a gray blustery morning in Hackney Downs. A man with a dog stopped nearby and asked 'what's that mate?' to which I replied 'a radio antenna, I'm trying to catch the signal of a weather satellite'. He gave a thumbs up and said 'so it's a weather thing? a weather thing?' I nodded, and he walked off without further questions. I had apparently given a satisfactory answer. Yet I wondered what kind of 'weather thing' he was convinced I was operating.

Storm Isha has been sweeping across the UK this weekend, with amber weather warnings issued by the Met Office in many parts of Wales, Scotland and Western England. Though the conditions weren't that bad in London, I stayed in the back garden of our flat to keep sheltered from wind.

Wind has changed the surface of the park and neighbourhood overnight, leaving large piles of torn leaves, knocking down branches, ripping coverings off parked motorcycles and bending 'for rent' signs on their axes. Whistles and howls echo through the streets and across the downs, joined by the sirens of ambulances and fire trucks. On local radio this morning there was mention of wifi and phone service cuts. This is London in the aftermath of Storm Isha, which has swept across the southeast overnight. Its long arm is dramatically visible in the satellite image I captured today – curving over France, Germany and the continent, and spiralling toward Sweden and Norway.

In comparison to the windy and wet weather of Storms Isha and Jocelyn over the last few days, today feels calm, even balmy. I walked to 'Founder's Field', the highest point on the university campus, to set up my spare V-Dipole and test a new dongle (RTL-SDR V4). The atmosphere of the university is also calm, as if the machines of departments, university managers and administrators are hibernating.

The sky is a deep cerulean blue today – cloudless, and slightly purple in hue. I spent part of the satellite pass lying on my back looking up. The grass was so wet and cold that I didn't stay on the ground long, but the feeling of being engulfed in a January blue has stayed with me.

Abney Park Cemetery was muddy, wet, and full of dog walkers and strollers on this Saturday Morning. The density of the winter trees and the humidity of the air created a mist that felt appropriate to the vine-covered tomb-stones, monuments and crosses. I thought of the way early radio enthusiasts heard 'something in the static' that spoke of other spaces and times of the past and future. I pointed my antenna at the moist ground, wondering if the static would pick up frequencies underneath.

Today is an unusually warm Sunday in London in January. Although the weather has been overcast, the clouds feel veil-like and thin, and the Sun either burns them up or pushes them away by midday. As I was due to make a Sunday lunch for some friends, I spent most of the pass alternating between looking up recipes on my phone and checking the satellite signal. By the end of the pass I had both a long WAV file and a list of ingredients.

Low, gloomy clouds hung over London as we gathered in the middle of a green circular lawn outside of the LESOCO building in which Goldsmiths design students study for their masters degrees and work in their studios. Deptford creek gurgled just a few metres away, though it was closed for access by a tall metal fence. A highway overpass arced to our east and a six lane intersection around the corner made a constant soundscape of motorbikes and car engines. In this context we huddled around my turnstile radio antenna and attempted to orientate our bodies in relation to the satellite orbiting overhead and the series of urban infrastructures around us. A constant interference pattern caused audible distortion to the satellite signal and produced regular and oblique lines in the image, like counter-currents of wind or a graphical anti-pattern.

The weather of Hackney Downs park close to 9pm at night on a Wednesday was surprisingly calm. A whispy wind blew blades of grasses but didn't manage to move dry leaves on the ground. I caught the wrong satellite – I had intended to capture an image from NOAA-19, and tuned to NOAA-18 instead – and unexpectedly started recording a 30 degree eastward pass. This first felt inconvenient because a line of Victorian houses blocked my 'line of sight' to the east. But the signal came through anyway, and this accident meant that I captured a dramatic cyclone swirling over eastern Europe and Russia. Seeing the image startled me- a dramatic disconnect from my experience of mild weather in the park.

I met the Centre for Research Architecture students on the top of College Green at Goldsmiths University on a brilliantly sunny morning of the 1st of February. I introduced the DIY satellite ground station we would use to capture an image from NOAA-18, and immediately there were about a dozen questions. Melodie held the antenna first, tracking the satellite from the southern horizon to a maximum elevation of 43 degrees. Excited chatter was constant throughout, and laughter rang out as Melodie and later Penelope tried different poses and antenna orientations. The atmosphere was joyful and lively, but as the pass came to a close, the group was happy to return inside to warm up and look at the image in darker / calmer conditions.

London is gray and cold today, with a haze that feels like a soft blanket. On my way to buy bread this morning, the air made street corners, cars and shops look a little fuzzy. Being inside a bakery, and back in my flat with a warm loaf of bread and a coffee, was deeply comforting. It feels like good weather to be tidying up the house, changing sheets and watering plants.

Today I attempted to receive a satellite image from a pass that I assumed would be 'out of the sensible range' of my ground station. The maximum elevation of the pass was 13 degrees to the West, and I hadn't previously tried to receive anything under 30 degrees. Expecting to get nothing, I found a spot in the middle of Hackney Downs and held my antenna as high as possible to catch whatever radio waves could bend around the curve of the Earth as the satellite barely crested the horizon. Surprisingly, the signal was already visible at 13:28 and I had a reasonably strong signal by 13:30. As I watched the image load line by line, I realised I was seeing cloud patterns over Greenland and the north Atlantic, so far to the west that no coastlines of Europe were visible. Meanwhile in Hackney Downs a group of dogs played around me and the gray clouds hung low. There was something incredibly strange about seeing the North Atlantic so many kilometres to the west, while Saturday morning life kept unfolding in London.

A cold wind slowed me down on my cycle ride out to Hackney Marshes. Once in the marshes, I weaved between Sunday strollers, kids on bikes, canal boaters and athletes to find a corner of the marshes to set up my ground station. At first the NOAA-18 signal was drowned out by the characteristic signal of the Meteor satellite fleet, which caused a 'mound' of energy extending around 80hz to either side of the NOAA-18 signal. I started recording during this noisy occlusion, thinking NOAA-18 was about to pierce through (helped by Automatic Gain Control) but it took a couple more minutes for the signal to make it through the surrounding energy and noise. The wind continued to bluster as the pass progressed. A kind looking man with long gray curly hair and headphones stopped nearby and offered to take a photo of me. We spoke briefly about radio and satellites before he continued on his windy walk.

There is high wind today, it feels like gusts are slicing across the surface of the city, though it is hard to tell from what precise direction. The clouds are patchy and partial, like a fast-moving lattice, and sun pierces through in very quick beams that meet earth's surface and disappear again. I imagine that from the position of the clouds, it might be like a high-speed game of shadow puppets. What shapes they must be casting!

The westerly wind was so strong this morning that, on my bike ride from East London to Bloomsbury, I felt at times that the strength of my body wouldn't manage to move my bike forward, and I regretted my choice to cycle in the first place. I was sweating so profusely inside my green puffer jacket that, once I arrived in the square, I risked the cold air and took off my coat to try to air myself out. I coudl tell that passerby were wondering what a person in nothing but a thin shirt and blazer was doing holding a metal object to the sky at half past nine, but no one approached me. On my cycle home in the evening, the wind, as I hoped it would, practically carried me forward, so that the roads felt glossy and smooth.

Today is wet, cold, soggy and muddy. A storm swept through London last night, and pattered the windows of my flat for most of the night. Most commuters early this morning had an air of being half-asleep and were hunched down into their scarves and woolly hats, like sea urchins. Founder's field, where I collected the satellite pass, was empty except for me with my V-Dipole antenna and laptop.

Rain pattered on the windowsills all morning. Water pooled and ran down the glass, and mist seemed to hover in between the three story houses on either side of our one-way street, like a wet cloud trapped in a crevice of our neighbourhood. I contemplated staying inside with my antenna held out the window, but ended up braving the rain with a big broken umbrella and a long insulated raincoat. Once outside, I propped the umbrella over a bench and set up my laptop and dongle under its shelter, with the antenna and cables curling out. At one point during the pass, the wind moved the umbrella and its flimsy, broken side sent pools of water splashing onto the keyboard of the computer- which I hurriedly brushed off with the sleeve of my coat, hoping no damage would be done. A man in full high-vis weather gear with a wheelbarow that looked like a recycling collection stopped next to the bench and asked what it was I was doing out here.

A break in the rain allowed me to duck outside to catch a NOAA-15 pass. The sun had set already, and very few people were out in the park and nearby streets. I searched for a bench near a streetlamp and assembled my ground station. I sat on the bench in the orbit of light provided by the streetlamp and extended the antenna, its metal dipoles glinting.

My ground station merged with the wet grass and mud of Hackney Downs field this morning. Mud was everywhere- attaching itself to my antenna bag, on the RF cables, the antenna dipoles, my coat and shoes. Nearby a young boys' soccer team was playing a morning match, egged on by a very loud coach who kept yelling at players by name and asking them 'who are you playing for?!'. I had forgotten my phone so I took photos of my ground station with my laptop camera. They were dark and gloomy but they somehow captured the atmosphere of the field, the game and the intermittent storm clouds.

After a weekend of rain and mist, this Sunday morning is glorious, with bright sun coming through very soft clouds. The local Baptist church is in full swing and fragments of choir music and raucous laughter echo into the park from the church's open door. A small group of teenagers gather on the street corner in between the church and the park, angling their faces to the sun. As I recorded the satellite pass I was visited by a small grey curly-haired dog with a red collar who then sped over the wet grass in circles around me. I think about 'dog satellites' and speculate on what they might transmit.

I counted the seconds in the pass I captured this morning. Though the pass was of good elevation, and the weather is beautifully sunny and uncharacteristically warm, I truncated my recording and practically ran home with my antenna still assembled and my cables and laptop dangling. I was worried I would miss saying goodbye to my partner as she finished packing up and left for the airport.

As I hurried out the door and toward the park, I realised that an invisible drizzle had become a light rain. I grabbed one of the broken umbrellas by the front porch and went to the park anyway. Crouching under the makeshift shelter on a park bench, I assembled my ground station and tuned to the frequency of NOAA-18. I knew the pass would be very low in elevation – only 19 degrees to the East – but I was hopeful. After a few minutes of weak signal as the satellite struggled to crest the horizon, a clear image began to appear- showing what I thought were Nordic glaciers and reflective lake surfaces. Only a minute or two later, the unmistakeable 'mound' of Meteor M N2-3 appeared surrounding and engulfing NOAA-18. Though the NOAA signal was strong, it was simply drowned out by the much wider and more powerful digital signal of the Meteor satellite, like someone trying to whisper in a crowded bar. I stopped the recording early, reasonably drenched by the rain, and returned with the glinting shapes of Nordic lakes in my mind.

Ashen, cinereal, dusky, smoky, slated, drab, grey: this is how I would describe my experience of the weather today. It is in many ways unremarkable weather, as it is not very cold, nor very wet, nor stormy or very windy. It is simply grey- a matte feeling of the colour like it surrounds you everywhere, inside and outside, dampening even your thoughts.

All night the wind howled around our flat. It caused unusual squeeks and whistles in different rooms. As a worked alone at my desk in the living room, the smaller, more random sounds made me imagine other people in the house, so much so that I went into the bedroom and studio to check! The wind had calmed by the time I went outside to catch the satellite pass, but I kept thinking of the wind-people.

This is the first day that feels a little like spring in London. The air has that shimmer that happens when it is misty but also bright. The green of the grass of Hackney Downs is vivid, an invitation to lie down (which I did) though I quickly learned it was also very soggy underneath. The satellite image I captured has a small cyclone curling over the North Sea, its long tail curving and sweeping all the way to the coast of Morocco.

I was aware today that a meadow has its own weather. As I captured the satellite pass, I was conscious of the way the air in 'West Field' at Royal Holloway, surrounded by oak and plane trees, seemed denser than it had felt on my walk up the hill to campus. The open sky over the meadow seemed closer than it had when I woke up in London.

There weren't clear signs of rain when I left my house to go to the park, but as I arrived in the open I could feel a sideways blowing mist of very fine droplets. Once my laptop was out for a matter of minutes it was complete coated in water. I debated the risks of completing the pass vs laptop damage, and decided to keep going, though huddled over the computer with my body. I imagine I looked quite strange to passerby- a hooded person bent over a small screen, trying to hold an antenna with one oustretched arm.

My socks and shoes were already damp from weathering my morning commute to campus, and they got even wetter as I traipsed around the university grounds trying to find a good place for the satellite pass. The field to the back of Queens Building (where the Geography department is based) was virtually spongy with water. I decided to try to set up on a picnic table in the middle of two science laboratories. In full view of biological sciences researchers fiddling with pipets and samples through a bungalo window, I set up my ground station and hand-held the V-dipole. I was lucky that the first eight minutes were rain-free, but toward the end I had to lean my body over the laptop to protect it from drowning.

This was a social day in Hackney Downs! I was approached by two men and their dogs, and speaking to them took up most of my attention during the pass. The first was an older, very large man named Bill and his dog nutmeg, a medium sized, curly haired deep brown dog, maybe a kind of terrier. The second was a younger man with a very big and wide laborador. Bill told me stories of his father who had used radio during WWII to listen to the Germans, and later erected aerials at racecourses across the UK (for reasons I didn't entirely understand). He also told me about a lecture he had attended by someone called Chris Lintott that was about microwaves and radio astronomy. The second man whose name I didn't catch had set up an antenna on the roof of his second floor flat to listen to ADSB. He mentioned he had gotten a dipole and tried capturing a satellite image but was unsuccessful. He also asked if I was into amateur radio and when I said yes, he said 'you and about five other people in the world, right?'

The bulbs and magnolias in Hackney Downs have been blooming in wild and 'spontaneous' groups. Across the UK, magnolias and camellias are blooming four weeks earlier than last year. As if in counterpoint to the conversations I had yesterday, today two older women and their dogs came up to me as I was kneeling by the daffodil beds in the park. One of their dogs, a terrier with huge whiskers, had come over to check out my antenna. The women were both wearing dark sunglasses and wool coats, and apologised for being 'nosey' before asking what I was doing. One of them remarked, 'there must be a whole group of people like you out here, I have seen them around'. I replied I didn't know who this group was, but that perhaps she was seeing me, as I had been in the park with my antenna almost every day (though the possibility of a secret Hackney Downs satellite group stayed with me). A younger woman then ran up to us, apparently having gotten confidence from the older women, and asked more questions with a lot of excitement- she had assumed I was tracking 'geotagged' animals, like birds.

My allergies have been horrible today- so bad that none of my emergency allergy medications and measures are working. While capturing the satellite pass, my eyes watered so much that I couldn't read the frequencies clearly; once back inside the symptoms didn't let up. When this happens I find myself desperately searching for the cause, but the thing about allergies is that sometimes there isn't one that is clearly defined. I am speculating about dust, springtime pollen, a low immune system, or lack of sleep- but none of these feel like the obvious source.

Today is the first day I felt a slight note of spring in the air. When I woke up at 7am there was already plenty of light in the garden. On my cycle ride to Bloomsbury, my hands didn't feel the bite of cold on my handlebars. I was overdressed for the temperature, and had to unzip my coat halfway through the ride. Later in the evening I perched on our flat's back windowsill holding my radio antenna in full exposure to the night air.

The university campus is coated and swathed in fog today. I set up my ground station on the near-end of Founders Field and could barely make out a group of students smoking (or just breathing in the cold) on the picnic table on the other side of the field. I met some colleagues in the local cafe afterward and they mentioned the fog to me too: 'it must be nice to see out of the fog today'...

A cold mist is hovering over Hackney today. Fewer people seemed to be out with their dogs, though it could also have been the timing of the satellite pass. However a group of people had gathered on the far side of the open field near Downs Road, bikes fallen sideways on the grass. They were stood in a wide circle doing slow movements with their arms and legs. As they were mostly dressed in long puffer coats and thick scarves, and because of the blurring fog, they looked like people made of cushions or marshmallows, moving slowly in coordination.

I am writing this weather note on a laptop that has been stepped on by a dog. I can almost see the outline of a paw on the lower right hand side of my laptop keyboard! While I was out in the field this afternoon, a man came up to me and asked what I was doing. He said he was following groups on Facebook doing similar things, but had never tried himself. He seemed genuinely interested in learning about open-weather and as we spoke his dog circled us several times, getting in the midst of the ground station and possibly changing the frequency I was tuned to...

A light rain is forecast to fall all day today. It is coating the street, parked cars, trees, bricks and asphalt in a layer of water that is perpetually replenished from the sky. In weather like this, I wonder how the bugs and creatures of the soil are doing. As water logs the pores between grass roots and humus, do the smaller creatures begin to swim? do they breathe underwater?

This Monday in London in early March is grey and dark. I had the living room lamp on for most of the morning while I was on zoom calls. I was several minutes late for the low-elevation NOAA-18 satellite pass at lunchtime but I'm still glad I went out to the park, as I met a young mom pushing a stroller, who stopped by to ask what I was doing. I showed her the clouds slowly forming over the South Atlantic, and we spoke briefly about the weather 'above and below'.

The darkness of yesterday has bloomed into spring rain today. Sitting by the open kitchen window, I could hear the pigeons cooing on the roof, perhaps making use of the partial cover of the chimney wall. Many people walked by on Downs Road, though their umbrellas and quick paces meant that they kept their eyes on the sidewalk, oblivious to a strange metal object being held out of a third floor window.

I went for a very low pass today – only around thirty degrees over the horizon – but thought I could get something from the top of the fire escape at the back of Queens Building where the Geography Department is situated. Unfortunately there wasn't much of a signal, and for several minutes at the height of the pass, bursts of interference blocked any chance of clear reception. Still, standing at the top of the fire escape gave me an amazing view of the residential neighbourhoods to the East of the university campus, and I could clearly see airplanes taking off and landing at Heathrow Airport, just over the reservoirs.

I wanted to field the ground today, so I laid onto the grass of Hackney Downs while capturing the satellite image. It was wet, yes, and musty too, and it smelled a little like unhealthy compost and dogs, but it was nice to feel my whole body flat against the surface of the ground. The air was cool and mild and lots of people were out in the park, some staring at me as they passed a safe distance away.

An animated wind is bending tree branches, ripping petals off magnolia trees and making waves in the deep green grass that has sprung up in parks, squares and pavement-free soil around Hackney. En route to a pharmacy, I stopped in a small park in between the Greville and Rogate estates. A tower block, wrapped in blue fabric, was being constructed (or refurbished) at the far side of the park, sending drilling and hammering sounds into the wind.

The sun came brightly through our windows this morning. Hackney Downs was brimming with activity, including the usual small persons' soccer practice on the open field. I set up a good distance away from the soccer, but still two balls came my way, kicked high into the air by players whose fluorescent jerseys came down over their knees.

A gentle rain fell for the first half of the morning but conveniently began to let up before I headed outside to the park. The grass felt warm somehow, even though it was slick and waterlogged. As I stood with my antenna in the usual field, reflecting on the horizon, a jogger passed close by and in the space of twenty seconds we had a brief exchange. As he ran off he remarked 'the things you can do in the local park!'

Last night, while sitting in the corner of the park on a bench under a streetlamp, an older, long-beareded man on a bike stopped, circled around, and told me I was 'too far into the park'. He advised me to go to the edge of Downs road to be safe, and added 'you are my daughter too'. This encounter stayed with me as I went back to the park this morning for a satellite pass, and looked at the distance between the bench and the streetcorner – a matter of metres – but in the dark, perhaps much more than that.

I perched my ground station on a forked tree trunk that lies on the grass in Hackney Downs. The bark and most of the trunk is wet but, unlike fallen trees that I've seen in forests, it doesn't feel like its decomposing. I wondered whether this tree has been preserved in some way, or whether its decomposition is slowed by the relative bareness of its surroundings.
