                  ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 I started checkout around 16:30 tonight and we were opened and cooling by
 sunset (17:20). Povilas was taking cals earlier in the day and Varsha
 started her biases and cals shortly after sunset.
 Seeing was fairly good at just under 1 arc sec until a cold air mass came
 in just before 20:00.  The seeing rapidly went up to over 2 arc sec and
 then settled back down for the next hour to 1.5 arc sec.
 Humidity closed us around 22:00.  At 04:20 there was no chance that we
 would be opening with the fog and precipitation outside so I called it a
 night and shut down.
