Last evening the sky looked promising but before it was dark the
low clouds had come down to the surface. This morning at 03 UT
the sky was clear. Unfortunately within 40 minutes low clouds rolled
in over the hills. Could image just a few sats.

The Unid from Nov 26 was IDed by Ted Molczan as AEOLUS (18066A / 43600).

The three imaged Starlinks all got bright when descending low in the east.
45875 and 45876 were 5 sec early on 5 day old TLE.
