Clear sky, albeit with some very thin cirrus during the first pass. Second pass
was very clear.

USA 245 was imaged during two passes. It flared brightly to mag 0 near 19:49:20
UT, just above eta Uma.

It was some 3.5 minutes early on my approximate elset from yesterday's recovery
imagery.

The improved elset below is based on my observations yesterday and today and
those by Alberto Rango, Cees Bassa and Leo Barhorst today:

USA 245                                                 269 x 1006 km
