On 1995 Aug 29 at about 01:30 UTC (Aug 28, 21:30 EDT), while watching Mir pass in my northern sky, I noted an unknown (to me) object moving to the right, essentially parallel to Mir's path, but much lower, and perhaps a half- to one minute earlier, passing below Polaris at about 01:30.5 UTC by which time it was fading (presumably as it was entering the earth's shadow, which Mir itself did a little later. I first noticed this unknown object near Beta UMa at which time it was at approximate magnitude +2.0 moving towards the right - in fact initially I couldn't understand why Mir was appearing much lower (abour 20 degrees) lower than predicted! Does anyone have a clue as to what this object was? My northern sky was rather hazy, but I don't think this was an airplane. Did a piece of Mir undock? My position was: North 40.067 deg, West 074.222 deg, 111 feet elev. Thanks in advance!
