              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
About an inch or so of snow on the enclosure when I checked during twilight. We were parked south all day but just not enough sunshine to melt the snow (clouds cleared late in the afternoon).  With the snow on the enclosure I notified the observers we are closed for the night.  We also were still on generator power at sunset and the humidity was too high.
We wnet back on mains power at Midnight.
Clear most of the night but high humidity.  No new snow overnight.
Telescope left parked Sout.
