              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
We had a mostly clear night with some amazing seeing most of the night! However, northern winds blew, with winds gusting at 35 mph, and the seeing started to degrade. The UVa class finished up their second night and "discovered" a cataclysmic variable! There was much excitement until we realized it was U Gem. Ah well.
No problems on the 3.5m tonight. Arcsat was another story.
