Well at least I think it is a meteor/piece of space junk.... Looks to be tumbling/changing attitude as it moves. I didn't see it live, the downside of imaging!
edit - on closer inspection I wonder if it more man-made - possibly some regular pattern in the pulses?
Slow revolving satellite, seems quite regular so not tumbling out of control ata aguess. They sometimes do that to equalise temperature for satellites that do not need to mainatain orientation.
