              ------------- ACTIVITY LOG --------------
Observing Specialist:    J. Huehnerhoff
Spicam started warming during the day.  Recharged system and leak tested
in the afternoon.  Took bias's until user logged on by which time the
bias' was at normal levels with a good standard deviation.  At 21:30
spicam started to warm, observing with spicam was stopped at that time.
Threatening clouds at the start of the night.  Opened when clouds started
to thin, moderate cloud cover till end of first half, clear the remainder
of the night.
Several motion errors tonight.  One in the Southwest at 01:20MT at an
az/alt of -40/36 and several others in the Northwest.  A bunch of these
occurred at 04:35MT when trying to slew north from the west.
