              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
Had to reset the Agile heartbeat at checkout. Obs0 had some weird aliasing going on with the window shadows too so I restarted it.
Tonight was totally overcast with lots of radar and elevated 1-micron dust counts. The rain alarm went off a few times but we didn't get much actual precipitation, and the dust was mostly over the closure limits.
We did an impromptu in-dome Apollo training session, and found that the guider camera isn't working.
We gave up for the night at 04:00 with no real signs of imminent improvement.
16C and low humidity at the start of the night. Temps came down to about 9C, humidity went up to almost 50%.
