              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We started out with clear skies but strong winds from the west.  The basin was very dusty but it didn't seem to be climbing the mountain.  Although we never had an overcurrent due to wind, on a few targets I could see it pushing the primary mirror around so I asked the observer to move further east.  Patchy clouds started moving in later in the evening, but there were still some clear periods.  When the looming radar signals spread into Otero county and the clouds were preventing guiding, I finally said it was time to close.
Despite radar above and all around us, the precipitation sensor had not gone off by 6 am.
