              ------------- ACTIVITY LOG --------------
Observing Specialist:    R.McMillan
Clear skies and good seeing for nearly all of first half.  Shortly before
midnight, the wind shifted and clouds moved in, so I closed. Continued
clouds, high winds, humidity, and snow starting at 04:00.  No significant
accumulation.
