              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
During checkout I noticed that the NA2 rotator was off. I rotated it to 0 but found it was still off, so I zeroed the rotator. It needed a correction of 1.28 degrees. I checked it again at the end of the night and there was no issue. I added to PR 1946.
NICFPS is back! I filled it at midnight and dawn.
What a great night of science! We had good seeing (it  was 1.14" at the beginning of the night but I forgot to hit the start button to record the seeing...again), no clouds, no moon, and no wind! The NA02 class completed their final night of observing and, through all the yawns, I could tell they had a great time!
