              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started out stormy once again. Funny enough, we didn't actually get any rain, but it fell all around us. I thought the night was a goner but, shortly before 1am, the winds kicked up and the storm completely cleared...for a few hours.  JH02 wasn't able to use the remaining time (they needed at least an hour) and donated 0.4 hr to CU05. Seeing was good but clouds started rolling in around 4am and we stopped early due to threat of rain.
No problems tonight.
