              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
We had a thunderstorm this afternoon and had a power dropout but we were back on utility by this evening.
The stripchart mac CPU was at 100% but computer not frozen; process "Strip Tool" using 160% CPU so I force quit it. This killed the az alt error plot, so that one was the culprit. I closed and restarted all stripchart graphs; CPU usage went back to normal.
Mirror covers had to be reset (as expected).
ARCTIC was unhappy at checkout with all quads at high constant values. Both UL and LR quads dropped with arctic init, but only UL was a pain to get back. I recovered the quads at the start of the night as we had a lot of radar and clouds and weren't going to get on sky anyway.
There was a lot of radar but sadly no more precipitation after sunset.
We finally opened around 04:00 when the radar dissipated and we could see some stars again, and got about an hour on sky at the end of the night through the clouds.
