                ------------- ACTIVITY LOG --------------
Observing Specialist: G.Saurage
Clear skies. Photometric most of the night. Strangely warm and dry.
Structure and Dome Air temps went out sometime around 10:20.
There was a call for a GRB tonight. The 1st half observer was gracious
enough to give them an hour at the end of his night. So, from midnight
till 1:00 we tried to get GRB observations. However, a clear plan of
action was not really established. DIS was the instrument mounted, so we
tried first taking deep images with the DIS slitviewer. It could not be
seen there. Then it was decided to put on SPIcam, which was done at 12:30.
I stayed in the dome so I could switch the instruments back since 2nd half
was using DIS. But there were some user problems with SPIcam and we were
running out of time. So then I ended up putting DIS back on. No real data
was collected for the GRB.
Seeing was much better tonight.
