              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
At 21:37 there was a power flicker and the az axis stopped and had to be reinitialized.  The DATAQ stopped updating and needed to be restarted (with a power cycle) at 04:30am.
The night started with threat of rain but it cleared up at sunset.  We had a few clouds at the beginning of the night and then towards switch over.  However, those cleared up after an hour.   While things did become clear, the haze was a pain the butt and was killing our transmission, but the seeing was great!
