              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Still on generator power and dicey weather.
The skied did improve during the course of the night, although we saw clouds hanging just to our S.  Unfortunately the humidity stayed in the 70-80% range for the entire night (going over closure limits a few times), which was a little too close under the current circumstances.  Luckily we didn't have any generator issues and hopefully they will have the mains restored by tomorrow.
