              ------------- ACTIVITY LOG --------------
Observing Specialist: N.Ule
Some light cloud coverage for the first half of the night, cleared up
completely by 23:30.  Brief power drop at 00:35, had to reset the motor
from the intermediate level, returned to normal operation at 00:39.
Apollo could not be run, was lacking deionized water.
Clouds rolled in again starting around 02:50 until about 03:50 when it
cleared just enough to get some observations in.  From then on it was
difficult to get anything.
