              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
Tert rot to BC1 from NA2 failed during checkout with "?LMSTOP clamp failed to fully close" error. Moved to TR2 and then to BC1, which worked.
We had a little rain during checkout and were barely rained on a few more times during the night.
Radar and heavy clouds along with the rain kept us closed most of the night.
We were finally able to open the dome at 05:00 (JH05 donated their last few minutes to WY02) and even got a few photons between the clouds!
