The brightest candidate, and closest in time, seems to be the 
Russian Zenith-2 rocket , USSPACECOM #19120, at 01:57 UT over
gamma Cassiopeia.

This is 10.4 * 3.9 m, and usually quite bright. 

Interestingly, another one of same type, #17590 crossed 
Cassiopeia in the opposite direction, 3 minutes later.

These rockets are very nice soon after launch, when they
ususally tumble rapidly, and flash about three times/sec.
At this age, they have periods like 20-100 seconds.
