              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
I was able to get throughput tonight on two fields, but the seeing was iffy so I'm not sure how good the data will be.
When we attempted to move to Shack to test collimation, the galil appeared to spontaneously restart. I tried to document this as much as I could in the engineering email. Once we were able to get the homing process done without typos, the mirror was homed without further issues.
We were not able to collimate as the cals stage for the Shack appears to be stuck in the light path. Russet sent a PR.
I ran a 100 pt pointing model but did not implement the results. The run did not finish until near dawn and I simply wasn't able to clearly identify the outlier starts.
