                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: Camron Hastings
 I opened to begin cooling at 16:00. All startup went smoothly again
 tonight. High winds, but clear skies. I took flats in 6 filters
 tonight to make things easier on Rene's program and the second half
 observers.
 2nd Half Observing Specialist: Russet McMillan
 Second half went smoothly.  The seeing and humidity were both bad for
 a period around midnight, but the seeing improved when the humidity
 dropped.  Fast-moving orographic clouds, invisible on the satellite
 or radar, began to move in shortly after 04:00, and the telescope was
 closed at 04:25 as the clouds grew thicker.
