It is the third day after the spring equinox. When spring arrives, we tend to know with a certainty that perhaps only the onset of autumn compares. I woke to bird song. It was only 5 am yet a Blackbird's voice cut through the night. I have seen the Blackbird during the day, perched on the balcony railing next to the bedroom window. It sung for perhaps 10 or 15 minutes before other birds joined, and the dawn chorus kicked in. I lay in bed in the greying light and wondered: how does the first bird know when to sing? It felt as if the Blackbird had sung up the sun, not the other way around.

Equipment troubles finally subsided for today's pass, resulting in a pleasingly expansive view of Europe and parts of North Africa. One interesting aside is that the wind was such that it blew through small gaps in the antenna, making distinctly musical notes in the process - can imagine a speculative art project in which the antenna is turned into a sort of instrument, working alongside the distinct notes of the NOAA transmission coming in. It would be quite the composition!

"That's so MacGyver!" says a blonde woman with a dog when I explain my tape-measure Yagi-Uda antenna. She and her friend / partner chat to me for a few minutes and walk off yelling back funding schemes that open-weather could apply to. "Welcome Trust.... Discovery Grant! Check it out!" I hear as they leave audible distance. I wonder if I've just met an arts and culture boss of some kind. I had come out to the park around 10:20am to catch a NOAA-19 pass that would pass over London at 90 degrees in maximum elevation- an elevation I have only rarely seen in my whole career capturing satellite images. A boy's football team is practising in my usual spot, so my reception is perhaps not as perfect as it normally is when I can see a perfect diagonal North-South across the Downs. Spring is everywhere today, in shooting daffodils and unfurling leaves. A twiggy plant that I had previously identified as a Serbian Lilac in my front garden reveals itselt to be a sycamore tree as its leaves unfold.

It was overcast and dry. Some sun was peaking through. It got a bit windy at times, but there was usually a nice gentle breeze. It was about sixteen degrees Celsius. The satellite pass was really interesting to see. The experience was quite grounding - being connected to an orbiting machine in the sky.

Software problems caused frequent glitches in the audio stream, resulting in this rather "striated" sounding, despite an otherwise excellent signal. A reminder, if there ever was, of the fragile chain of material structures and processes that enable these activities - and of how this fragility emerges from their status as constantly performing 'agents' in the world, rather than the typical image of technology as always fully tamed, always fully obedient to human imperatives.

Blue skies for installing the ground station the day before this first image uploaded, we worked together with Ray from Goonown. It was warm and springlike in Helston, the magnolias on the streets around CAST had just come into their element. We thought we knew the aspect of the building but we were surprised by the direction of true north, we had been looking closer to north north west. Spent some time pondering magnetic deviation, unsure if the smart phone compass already accounted for it, wished we had a proper compass with us. We chatted with Ray about the dry weather and how different it’s for them planting this year compared to last. A few passers-by already stopped and mused on the new feature - ‘are you installing Sky TV?’. The computer, sitting under the desk of the buildings office, seemed to be working okay and we were intrigued to see if it would upload. Ruth listened to the audio file before we saw the first image, as the automatic upload didn’t work the first time - a strange sound. Seeing this first image we couldn’t quite comprehend any features poking through the noise, it wasn’t until someone else pointed out Scotland and Ireland beneath the clouds, upside down. We worried the granite building was obscuring the reading too much but were excited to see if we could trouble shoot the image with help from Sasha and Soph. The Seaweed Institute

Santa Monica Pier, United States

Captured a satellite pass today from the Santa Monica pier. Sunny and 16°C, a typical March day. Two months after the fires that leveled most of Pacific Palisades it is hard to tell anything happened in the rest of the LA area. The pier is full with the usual sight-seers. Bike riders and volleyball payers do what they do. You have to know where to look for the evidence. At the water's edge interesting patterns are made of burned vegetation and ash. The new presidency is hard at work making us look the other way with declarations of the Gulf of America and Mount McKinley. Apparently in America there are now only two genders. Meanwhile thousands of government jobs and agencies are being canceled. Services related to education, the National Parks and medical research are no more. And the Coast Guard Academy can no longer mention climate change in any of their trainings.

The alps curve with sharp icy edges, highlighted against the otherwise dark land surfaces of Europe. Around campus, and across parks in London, purple and yellow bulbs are pushing through the grass. I fight the urge to lie down on the grass and smell them up close, aware of surrounding students.

A very low 22 degree pass on a cloudless March afternoon. After weeks of being trapped under a sheet of grey the scattered blue light of the sky is so very welcome. I sit listening to the beeps of the pass watching a sleepy Bumble Bee wave around after his winter rest. Yellow Hazel catkins tremble on a slight breeze and seem to vibrate in time with the click of the radio waves. For this brief moment, everything is connected. 11 degrees Celsius 54% humidity 1032mb

First notably warm day of the year, unusually so in February, at 15C. Blustery. Malfunctioning equipment cut off both the start and end of the transmission recording - which also survived a complete computer crash.

Some sunlight was very welcome after many days of freezing, rainy weather. As I tracked NOAA-18 over the Atlantic at only 31 degrees maximum elevation to the west, three women and a dog came over to ask what I was doing. One of them turned out to be a former physics teacher and professor, and we discussed satellite orbits. The small, short haired dog kept bouncing across my laptop. During the pass I thought of a recent rebroadcast of a 1970s radio interview in which the host described February as a month that is 'honest'. It doesn't lead you to think that things are any different than they are. It is miserable, and everyone knows it. Cheerful holidays like Mardi Gras are balanced by Ash Wednesday. If you make it through February, the host said, you will make it through the year...

Mostly sunny skies and 16°C - pretty normal for a southern California February. After 8 months of no rain, the last 3 weeks has helped to finally put out the fires and bring the area out of fire danger.

NOAA 19 clear sunny blue sky with 7pmh winds. Keeping the antenna close to our bodies helps to receive a clearer signal. Standing in the sun with our eyes closed and listening to the sound is meditative. Fascinating to see the image and imagine ourselves as a body in a green field, but also a global body in this vast sky
