On Dec.19 I had the first clear night in months (except for brief periods
when I managed to see an Iridium or a NOSS/Lacrosse rocket).
At 16:55 UT, I saw a predicted -7 flare of #25342, also photographed
on 400 ASA Fuji with 135/3.5.
I went out two minutes before what I thought was shadow exit of #25105,
and saw a single bright (-6?) flash left of gam UMi, right on the track,
at 17:55:35 +-5 sec UT, but was unable to find the satellite afterwards.

Before that I made the following positional observations (1950.0)
