              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Sutherland,A.Townsend
Thank you to Amanda for all the help tonight!
Dust kept us closed at the start of the night.
"Could Not Compute" error on tspec rotation on first slew at 2:15am. Did axis init rot and a test rotation and things seemed fine after that.
No further problems tonight.
