				      ACTIVITY LOG
	We opened tonight at 19:20 to start cooling. The weather seems to have
departed for the time being! GRIM was mounted and we were on the sky 20
mins ahead of schedule. Everything seems to be functioning normally,
except the dew point sensor. I am disregarding its readings in favor of
personal observation tonight. Currently it reads a dew pt depression of
2.3 degrees, but nothing outside feels remotely like condensation.
During times of high risk I am checking the enclosure every 10 minutes.
	We closed at 21:10 due to high humidity, low dew point depression,
lightning and thunderheads to the east, and wind gust speeds exceeding
40mph. Other than that, it was a pretty nice night. Though winds tapered
off to about 33MPH around 03:30, the dew point depression remained too
low to open.
