Alongside these soundings I have been conducting another small project of my own - Nephoscope. Named after 19th century instruments for measuring the movements of clouds, my digital equivalent analyses these movements using the camera in my phone, using the data to then generate a form of poetry over the video feed. I like this idea of these two electronic instruments, satellite and nephoscope, working together to map and articulate the atmosphere along two different registers, and at two very different scales.

It is always pleasing to watch the signals of two NOAA satellites together, on the waterfall.

Last week was the hottest May day on record in the UK, today is decidedly cooler and greyer. A reminder that Spring is always an unstable threshold, like any season.

This image was gathered as part of a class workshop I ran today, as a simple way of bearing out the radio networks that underpin much of our contemporary environment.

Calm, cool conditions were conducive to a clear and crisp recording, marred only by my perennial foe during recent efforts - software glitches, cutting out the audio! I had a chance to reflect at a conference yesterday on the nature of these sensory undertakings, the registers and durations that they speak to. Glitches themselves manifest across multiple durations, and begin to inscribe their marks long before they become apparent on recorded media. The deep, granular hardware incompatibilities that will forever prevent this computer from generating a clear image were established several years ago, when it was first built, and will now be registered in this archive for as long as it is sustained. There's something pleasing about this - a sense of material traces across time that the usual quest for the perfect image (the perfect sensory recording) would otherwise strive to eliminate. There are long histories of Western onto-epistemic-political imperatives at work here, and these are now manifest in the technologies and techniques that delivered the signal processing behind our digital world - along with its surrounding marking rhetoric of perfect reproduction, and seamless, immaterial operation. The computing of angels. All this observed - I am presently dredging up an unusably 'glitched' computer that, nevertheless, once gave vastly better recordings than the more modern machine used here. I hope it might deliver a clearer image for the next pass, in 30 minutes time!

Cable problems mean even the slightest breeze generates noise in the image - but this does result in the rather pleasing fact that the weather itself affects the image generated. You can see when significant breezes come in as striations over the image.

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.
