identification problem

this is a greatly reduced four frame animation made of 4 2 minutes exposure
made by a Canon 10D hooked to a 115/805 LZOS (ahem) refractor at a 20 secs
interval. The object passes right between 14 vul and M27. The width of the
field being approx 1.5 degrees it seems the object roughly travels at a
speed between 1.2 and 1.8 degrees per 10 minutes (mental note, check trail
length and angle) which gives an eventual orbital period above 24 hours, up
to approximately 48 hours. Seems too slow for a normal satellite. The
closest match I could get with A. Pouplier's suite is Cosmos 641, but it's
supposed to be much faster and 4 degrees below.

Too slow for a satellite, but isn't it too fast for an asteroid?

I am a total newbie in this identification matters, more than a short
answer, I am interested by any pointer describing methods to identify such
objects. Thanks in advance!


Could it be a geostationary satellite?
