              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray & A.Townsend
We had some strong winds in the afternoon but not over 35 mph. The sky was clear and the seeing wasn't too bad.
The CU01 had their first night of training and did an amazing job! I don't know how them made it through all of A half when they were taking 1 min exp. So many stars...
The winds started shifting towards the north and we had some pollen spikes. I caught it late but closed when I checked the pollen between GS01 and AP01.
Dataq is frozen again.
