Observed all night from 23:25 to 9:38 UTC.
Conditions were Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing 1.4 arcsec, Clear, Winds Calm
   Mid: Seeing 1.4 arcsec, Clear, Winds Calm
   End: Seeing 1.4 arcsec, Clear, Winds Calm

Observing Summary:

You will notice some mistakes in the Logs. They have been corrected though (wrong coordinates for HD193727 then wrong osbpar used)
Charles, we should move earlier than LST 23:15 since the telescope reaches it's limits while pointing at Aql X-1. I think 23:00 would be fine.
Differential magnitude of Aql X-1:
R=2.2 (no obs. in V band as explained above).

No problems at all.
