              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started out clear and slightly humid.  We opened on time and had fantastic seeing, 0.5"! The Pillar of Life never looked so good!  However, amazing as it was, the humidity kept creeping up and we had to close at 22:36.  Shorly after, a rain storm hit and we remained closed the rest of the night.  While the telescope was closed, we zeroed the NA2 rotator and analyzed the contamination on the DIS red chip.  It has not improved but it has not become any worse.
No problems tonight.
