              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
There was some strangeness during checkout where NA2 rotator would not rotate when commanded(still reading buffer empty). I did an axis stop and then an axis init once more, and the problem went away.  Evening started out with clouds, but then clearing. Humidity began to spike high even before sunset, though. There were also returns on the radar near us, so we did not open right away. Around 23:00 the humidity seemed to be trending downward, so we opened. It did not last long, as humidity shot up again and we closed around midnight. We stayed closed the rest of the night, which due to GS04's very dim target, meant 4am.
