We woke up to news of US airstrikes on Iran. Operation 'Midnight Hammer' was later outlined in a press conference at the Pentagon as an 'overwhelming success'. Trump's actions were commended as 'bold and brilliant', and soldiers were called 'warriors'. God was invoked several times. Watching from London, I couldn't help but remember Brian Massumi's analysis of speeches by Ronald Reagan, and the way the content of Reagan's speeches mattered less than the way affect was 'modulated' on screen. Today, affect was heavily 'modulated' with word choice, repetitive gestures, and an absurd performance of stature and power. The longest day of the year in the Northern Hemisphere passed by in a blur of heat. This weekend, London faced its first amber heat warning from the Met Office since 2023. At Loughborough Junction in South London yesterday, passengers were forced to wait in overcrowded, boiling train cars for up to two hours, and ultimately to walk along the hot train tracks to evacuate between stations. The dry, brittle grass of Hackney Downs was dotted with sunbathers but many people also hurried across, not willing to stop at the height of noon.

A fierce morning, sunlight pitching down, and a breeze that brings little immediate respite. The first of the summer heatwaves is here. Still sounding the remaining APT NOAA satellites where time and space permit. In recent weeks I have noticed a wandering band of noise, ill defined, which occasionally intersects with the NOAA signal, as here, and disrupts the reception.

Arbroath , Scotland

We’ve come over to the park in search of more open skies, but realise with the satellite travelling to the east the trees - a tangle of Scots pine, brambles and elder - will be in the way. Still. The sun is getting lower but you can tell it’s close to the solstice: a long bright evening. I’ve roped Aaron in to join me, and we set up on a bench near the top of the hill, next to the water tower. Kids on bikes and wandering teens don’t give us much notice. Around where we settle the broom is already full of leafy-green pods, cow parsley is high and my hayfever is off the charts. The pond below is gleaming with the setting sun, and to the west there’s an open view along the coast when the beachfront opens up and the Tay joins the North Sea. I haven’t seen Aaron in a few days so I catch him up a bit about the End of Life Nowcast, and we reflect on the last one, during COP26 in Glasgow, laptop precariously shielded from lashing rain by a wonky brolly. It can be very useful to have a helper, whatever the weather is doing. I think of NOAA18 still circling, silently. Pointing the antenna at the horizon, I realise I’m bracing to hear nothing, but out of static comes the familiar tones of NOAA19, if a bit faint (due to the trees). Again the idea: ‘the static's like the sound of thinking.’* I should really get another USB extender, or tape it together, this one is a bit loose fitting and when it detaches slightly from the dongle the recording stops and I have to restart it. So, my recording for this pass is in two parts. Both about 5mins. If I splice the audio files together and upload the file, what happens? Thinking with the glitch, being happy with the lack of and resisting the idea of a ‘good’ or clear image is always part of this process. Need to remember this. A counter to the closed, fabricated smoothness and place-less certainty of the pin sharp google image. The space that these DIY processes open with their fuzziness, the image’s materiality written in the grain. *Tom McCarthy, ‘C’ (Vintage, 2010) pg63

In the hope that the APT continues for a while yet, I couldn't resist trying another sounding today. Main highlight, however, was a very close terrestrial encounter with some interested passers by! (* I would not normally go anywhere so close, of course, but these particular visitors made a bee line for me and then peacefully waddled by - although I did shuffle behind the antenna as they did so!)

I wasn’t sure what to expect today with NOAA 19, but a strong signal is still being received on APT. Will you continue the project if APT remains active? In terms of learning I have learned more of what doesn’t work rather than does work! Ferrite beads, position of the antenna, line of site not necessarily height, different antenna builds, directors, reflectors, element types, copper tape, wire types, skin effect, ¼ wave stubs, shielding, noise removing, software compiling, and a general “can do” spirit. VHF is ideal for inspiring and learning as it’s so hands on and forgiving if you don’t quite get it right, especially with the NOAA satellites. I’ve started looking at the Meteor M2-3 and M2-4, and perhaps I might try other satellites at the 1700MHz range, but I can guarantee one thing - I would never have even thought this was all possible from an amateur set up without having experienced NOAA’s 15, 18 and 19! They truly are astonishing.

FLY BY - Ode to NOAA-18 I watched and I waited as you were set to fly by A perfect night for reception, as we had a clear sky As you grew near, there wasn't a peep all of your speaking instruments were all fast asleep You are right over head! But the static remains I messed with the volumes, I messed with the gains I watched on my tracker as you slowly flew by my S-meter grounded, the waterfall was dry We bid you farewell, oh watcher of the sky and I will always remember you, as you silently fly by

2 Extra Images are NOAA 19 Encoded with map overlay and my Personal Weather Station Data. A big SHOUT OUT to open-weather.community (Sasha & Co.) for bringing this to life and allowing us amateur radio/satellite/weather enthusiasts to have a place to share our work. Another Shout out to NOAA-15, NOAA-18 and NOAA-19 for years of relentless service. I don't know your fate, but I hope its as deserving as the service you have provided over the years. We will miss your shadows and echoes, but you will always be remembered in the annals of communities such as this. Fly high and free.

Son las 11 de la noche y cae la lluvia más intensa del año sobre Valparaíso. Desde mi ventana veo las colinas del cerro del frente y una calle inundada con un río de agua bajando la quebrada. Una bruma acompaña el ruido uniforme de la lluvia, iluminada por los faroles de la calle. La ciudad está silente y vacía, tomada por el agua que cae y su suave sonido.

Saint André, Pyrénées Orientales, France

Particules have been in the air for weeks without interruption. Depending on their density, the blue sky, the clouds and the sun are indistinguishable. The sky is white, blinding.There's a veil between us and the trees. Today was a little bit better than it had been for several weeks. Yesterday I was even worst ; in the night it rained for 2 or 3 minutes and dust settled.

This is the first time I've picked up a NOAA satellite pass outside of NYC - I'm on a holiday with my close friends in rural Italy and it is unbelievably peaceful here - the dawn chorus/sound of cicadas at night is a far cry from the noise pollution of NYC...we just discovered a new birdsong from a Eurasian Nightjar - and it sounded like clockwork - or a faint chainsaw - it was beautiful and bizarre...I was scared we wouldn't pick up the NOAA 19 signal but after initial static it was so clear and was joyful to introduce my friends to SDR/to this methodology - one of my friends held the antenna for 15 minutes with impressive stillness - and we took a collective pause. And then to experience the decoded APT and the ephemeral cloud formations that emerged!! The last 6 minutes of the transmission were filled with static as seen on the bottom of the image - but I think I like that!
