              ------------- ACTIVITY LOG --------------
Observing Specialist:    J. Huehnerhoff
Photometric night with seeing stabilizing to around an arcsecond after
twilight.  Towards the end of the second half seeing was horrible, it
ranged anywhere between 1.5" and 2.5".
The wind also started to gust above 30mph around 04:00 MT.  I checked dome
at this time for any snow blowing into dome, it was all clear.
