              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
We started out the night zero'ing the rotator.  It only needed a small adjustment: -0.070
We tested the tertiary multiple times and found that it seems to fail most often after it's been sitting awhile, regardless of how much the telescope is slewing.
Collimation was adjusted with Shack....twice.
A pointing model was run but no adjustments were found to be needed.
Tspec instrument block was conducted with small adjustments needed.
The dataq had to be restarted around midnight.
