              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shugart
Dust and high winds kept us closed at the beginning of the night. They
remianed high, but not too close to closure limits during first half. Dust
counts spiked in 5 minutes during obersvation, so the mirror may be a
little dusty tomorrow. Opened again at 00:53. Ended at 01:12. Closed for
dust and nearby radar returns at 03:51. The weather did not improve enough
for us to open the rest of the night. Completed fills, and called it a
night at 06:00.
