              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
We had a little storm sitting to the southeast of us for most of A-half, spinning off a lot of clouds in our direction. We were able to open at 23:20 for the rest of the night, with very good seeing!
We stopped observing for about 15 minutes due to clouds at 03:35. I included this as time lost to weather but I didn't bother recording it in the On-Sky times.
Russet and I checked the APOLLO ACS and APD stares, and everything looks much better after the power supply swap. Yay!
No telescope or instrument problems.
