David Arditti’s Sky Notes from last Wednesday’s meeting are here. The other talks, including my George Alcock Memorial Lecture will go up on the main site soon. Unfortunately, we had a technical fault with the lapel mic so the sound quality in all of these is poor but hopefully not too bad.
Hi Nick, You showed an image of Arend-Roland taken on Oct 24 1957 by Waterfield, any chance that the trial across the comet image was Sputnick launched on Oct 4 which survived for 21 days?
I don’t think so. The flashes along the trail look like navigation lights to me. Sputnik 1 was a shiny sphere and so wouldn’t flash in that way. This is the picture I showed in the talk.
