    I arrived at the same conclusion as Ted. Cosmos 482 (E) is the sat I observed:

    In comparing the pass predictions for the two objects, I also noticed the time discrepancy. My time estimate of the passage of 72023E through the FOV is incorrect. I only recorded one split for this object, which I erroneously assumed to be the time I acquired it. It appears that I recorded the split further along in 72023E's track as it appulsed a star, but failed to make note of it. Post-observation, I was apparently preoccupied with documenting the positional observations I had just made of 03790B, my original target, and also noting another unid that passed through at 11:21:57 UT (Globalstar 52 Delta Rk, #25774, 99-031E). Typically, I record a split at first sight of an unid and, if I decide to track it, record one or two higher-precision positions so as to define the track which possible candidates must fit.
    
    72023E should be an interesting object for pre-dawn observers in southerly latitudes of the Northern Hemisphere the next few days. I see that its 210 km perigee is currently at 22 N lat (although now precessing into shadow).
