              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started off cloudy, with high winds and rising dust.  Slew tests had to be skipped on account of wind. We did not open right away for the same reason.  It began to clear and by 21:46 winds had died down enough to safely open.  Sinusoidal noise was observed on the az telemetry (last night as well...forgot to mention it in the log).
After 21:46 we observed all night.
