              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Rain and Hail during the daytime left lots of moisture around.  Clearing just before sunset sent the temps dropping and humidity above closure limit.
Power fluctuations during the day tripped the drive enclosure, reset and all was well.
We opened at 22:00 with poor and variable seeing.
We got 5 reflectors with APOLLO tonight.
