              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
Stayed closed at the very start of the night due to nearby radar and annoying clouds. We were able to open for about 40 minutes before some ominous clouds popped up with a quick rise in humidity and closed again for an hour. The sky cleared up and we opened back up at 22:20.
Closed again at changeover because of humidity, opened back up at 02:17.
Due to poor seeing we tried binning kcam, but 3x3 binning caused the error "sendCmd timed out: timed out". I did startNubs kcamera and kcam and that cleared the error; 2x2 and 4x4 binning worked fine.
BY01 finished at the start of twilight.
