Greg, congratulations on your recovery of 05042A. Here are estimated elements: USA 186 15.0 4.0 0.0 5.3 v 1 28888U 05042A 06353.77110617 .00010748 00000-0 11000-3 0 00 2 28888 97.9408 53.2839 0555000 246.2000 108.0092 14.72000000 06 The mean motion is based on my hunch that since the object was last observed, a major manoeuvre was made, most likely within a few days of Nov 14, when perigee was near the equator. USA 161 (01044A / 26934) likely would have manoeuvred about the same time, which would explain its non-appearance when Greg tried to observe it on Nov 21. As far as I know, that was the first reliable reported non-obs since the last observation on Oct 28. If I am wrong about 05042A's mean motion, and it is closer to the other extreme, say 14.77 rev/d, then after 15 revs it will be at least 5 min early, so I recommend an allowance at least that long.
