                 ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 Mark and Day staff cleared the snow/ice from the dome during the day.
 Special restrictions for tonight are close with sustained winds 20MPH+
 and/or gusts 25MPH+ and open with below freezing conditions only.
 With a broken anemometer (and Sloan being closed) it made it very
 difficult to determine site wind speed with any accuracy.  Mostly it
 was just guessing by going outside and listening to how hard the wind
 was blowing thru the trees.  I did use the NWS CSMN5 data
 (updated hourly, YIKES!).  We were about to open around 20:00 when the
 humidity dropped but unfortunately the wind gusts picked up above the
 25MPH closure limit.  The wind remainded gusty (with the NWS data showing
 gusts above the 25MPH closure limit Mark had set for tonight) so we never
 opened.
 I worked on web stuff all night.
