              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Rain this afternoon, and a good downpouring too.  Clouds kept us closed
until around 22:30.
DIS temps @ 20:00 219,186
DIS temps @ 22:30 222, 186
DIS temps @01:20 227, 187
Observer tried to abort a KOSMOS exposure.  The Abort did not abort the
KOSMOS exposure.  The stop button did stop it, but I had to do this
because their button was ghosted after their abort attempt.  This worked
without crashing the torrent.
DIS temps @03:35 228, 186
Clouds moved in at 03:10 and I decided to close as the satellite was
showing possible rain just to our South.  It got completely overcast after
this point as well.  The observer used the time for dome flats and darks.
No telescope issues tonight.
