              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The first night of shakedown!!
We had rain in the afternoon radar everywhere nearly the whole night. Around 1am the dust spiked over 30k and it didn't come back down until 6am. We were able to open on sky for about an hour to do some collimation exposure. Amanda and I learned what actuator adjustments would be needed but we did not make any adjustments as rain was coming up the mountain and we needed to close.
Task Completed:
- hub and tcc restart
- reset axes
- zeroed rotator -0.122
- restart parallels
- DOCUMENTATION!!!! Holy cow, I have a MUCH better understanding of collimation! But it's going to take all of shutdown to get things written up, diagrams drawn, and everything put on the new wiki in color-coated glory.
