              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
Photometric night with good seeing.
At checkout, gcam needed a startNubs, and then again in the morning when I used it to check the sky; we had a little trouble with pointing that might have been due to offsets.
Temperatures between 15 and 10C, humidity rose from 10% to almost 20%.
