              ------------- ACTIVITY LOG --------------
Observing Specialist:    J. Huehnerhoff
Spicam warmed unexpectedly sometime today.  The system was recharged with
gas and pumped on.  There were no problems the remainder of the night.
Seeing started out decent but around 0915MT rapidly worsened.  The rest of
the night was extremely poor seeing.
Several Azimuth motion errors when moving from the West to the North.
There where none when moving from the North towards South, so the problem
seemed very odd.  These errors occurred at 0335MT and 0455MT.
