As I leave for a workshop with a PhD student in Bloomsbury, early this morning, I set up my turnstile on the kitchen windowsill. Making sure its 'reflector' spokes are inside the window, and the cable is taped to the window ledge, I leave the flat. Upon returning many hours later - after cycling over 1.5 hours in total across London, through streets heavy with mist, smog and traffic - the antenna is still there, poised to receive. I wondered, as no one was in the flat when it recorded, whether the plants sensed what was happening. I wondered if the simultaneous recording of Automatic Ground Station 11 on the kitchen table, connected via a thick coiled cable to the turnstile antenna on the window, together with two other Automatic Ground Stations in T's studio (not connected to antennas) changed the conditions of the flat in some way. I enjoyed thinking of the three stations lighting up on cue, all attempting to track and receive radio waves from NOAA-19.
