              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
Dust for most of A-half, but we opened up for the last 20 minutes. We did not bother to focus KOSMOS. The weather was very nice otherwise!
TUI disconnected on obsA at 03:10.
Motion error at alt 72 doing a slew in place right after initializing axes at 04:22.
CU02 donated a few minutes to NA01 to finish up cals since their primary target would not be rising for a little while longer.
