I was imaging IC443 JellyFish Nebula last night with my Askar APO103 @ 700m focal length, and I noticed over the course of 5x 120s exposures, a small target slowly creep across the frame.

I've entered the observation details into the JPL Small-Body Database Lookup but nothing that returned matched the path.
Does anyone know of a resource I can use to identify this object if it's a satellite, and if not, what would be the next steps in registering it 'somewhere' ?
Cheers
