              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Bradley
open  17:35   18:32
open  19:55   23:38
Visiting observers:  Deqing Ren, Jiangpei Dou, Xi Zhang
Aided by myself and Russet
We pushed the humidity limits to begin with because the telescope was still very warm.  That trick stopped working around the time the clouds started rolling in, so we decided it was time to close up.  All in all, we thought things went very well for the visiting instrument.  Russet sent out a report about working with that instrument.
The rest of the night was foggy, cloudy and humid.  We never opened back up.  We gave up at 5:15.
