              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
Too dusty to open all night long; 1-micron counts max around 17000 early in the night but they never fell below 5000. We gave up at 05:00.
Russet and I did a little more Agile checkout this evening. The instrument is still having rotation difficulties, but the rotator is talking to tcc now!
We had no telescope problems.
