              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shugart
Clouds and radar in Otero county kept us closed until 20:23, when we
finally decided to open and try to push through the clouds.
20:50-22:30: We remained open but did not get more than one good exposure
of data through the clouds. We decided to close at 22:30. I looged all of
this time out to weather. An estimated 5 minutes of data was taken, so I
logged all of it to weather.
Opened again at 00:45. Weather held out for the rest of the night. No
technical problems. We closed at twilight for cals.
