              ------------- ACTIVITY LOG --------------
Observing Specialist:    R.McMillan
The good news: despite wind gusts topping 70 mph in the afternoon, we had
only a few short power flickers and no major utility outages.
The bad news: a couple of inches of snow, plus consistently high humidity
and less-extreme high winds, meant that there was no chance of opening.
I ran the snow program all night to help the wind clear the dome, but I
turned off the roof heaters since the temperatures were too cold for them
to work effectively.
Guy and I took some linearity data for the tcam slitviewer to try to
evaluate its usability for imaging.
