              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shugart
Corrupted Tspec images during checkout. Very high winds and snow flurries
kept us closed. The wind began to create snow drfits after midnight.
Accumulation amounted to between 0.5-1" by the time I went to bed. It was
too windy to run the snow program. I parked in the south for sun exposure.
Called it at 04:30.
