              ------------- ACTIVITY LOG --------------
Observing Specialist:    J.Huehnerhoff
Delayed start of observing due to weather. Light dusting of snow into the
afternoon.  While preparing to open after the radar returns moved away the
cloudcam had trouble starting.  Power cycling fixed the cloudcam.
High humidity caused terrible seeing for first half and the DIS slitviewer
shutter was sticking on every other image.  Focusing had to be done
manually through iraf due to the shutter problem.  Although it is a known
cold weather problem the instrument was nearly unusable.
Seeing was much better second half and continued to improve the rest of
the night.
While closing the mirror covers at the end of the night they failed to
respond.  Resetting had no affect.  See PR1206.
Parked facing south to melt any residual snow.
