              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
dataq needed a restart during checkout
at 3:07, TUI disconnected for an unknown reason but I was able to quickly reconnect.
The night started out clear and stayed clear! The seeing was good, the outflow from the east stayed to the east, and there were no moths. However, APOLLO wasn't responding so AP01 donated most of their time to NM07.
