              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend,R.McMillan
During checkout, Arctic would not connect. We had to start the Arctic ICC (it was not currently running) & hub startNubs + init. We also recovered the Arctic dropped quad tonight.
The sky cleared up quickly after this evening's rainstorm and we were able to get on sky right away.
However, just after focusing echelle for the B-half, we started getting radar returns nearby and clouds from storms to the north and had to close the dome. We re-opened at 03:45 to clear skies and good seeing, and stayed open until morning.
Optical cloud camera froze at 00:40, power cycling the camera and the router brought it back online.
