Hi Rob
at 80°altitude at that time of the night a satellite would have to be very high to receive sunlight,probably in the 10,000km or higher orbit,but then it would be so small as to hardly be visible.
I would say it is a slow reentry of a piece of space junk or meteor coming in at a shallow angle,or even bouncing of the atmosphere.
I have seen bright satellites at just about every hour of the night while observing but they have been close to the SCP.
Just a matter of interest,I have seen iridium satellites flair more than once.
Cheers
PS I hope Robert is joking. ?
