Sunset. I started the run during twilight. It gives me the option of using some early frames if I want to for extra colour (such as the first image

). Both these images are made from the same set of data, I just dropped some of the earlier frames for the second one to get a darker sky.

Al, the second one seems to have captured what I think to be an Iridium flare? or some other tumbling satellite stuttering across the frame?
What do you think?

Nice work, Detective Chris!
I think its a strobe on a plane. It's very regular, and while a tumbling satellite would also be regular, the angle to the sun would not be and any flat reflective surface would quickly fade. Actually I just checked the individual frames: definitely a plane. There is a fainter strobe beside each bright strobe and a red strobe just offset but always in the same orientation to the other 2. 31 flashes in a 30s exposure and about 5 x 30s exposures to cross the FOV.
