              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The wind was high at the beginning of the night but did not produce dust....until right as switchover when the dust spiked and we had to close for  about an hour.  Wind stayed a bit high but we were able to stay open and had moderate seeing. We have a new minion trainee from UW who is learning the ropes quickly and is basically trained in one night!  But decided to stick around a few more days for obs.
No problems tonight.
