                               ACTIVITY LOG
The telescope was opened at 19:40.
Michael Strauss was observing for the first half of the evening.
COMMENTS:No problems tonight; the camera and telescope worked fine.  There
were some unexplained
focus changes in the middle of the run, and the seeing was never very good.
But we were
happy to get some clear weather!
Scott Anderson was the second observer.
COMMENTS:We were open throughout the 2nd half, with good 1.2 arcsec seeing,
fine
transparency, etc. SPIcam, guider, and telescope all performed extremely
well, and support was excellent. A very good night.
Thanks Tia!
