                ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: G.Saurage
Complete overcast at sunset. Local radar activity until about 9pm, when
the skies cleared a bit driven by high winds. Too high to open. Then
around 11pm the humidity began a slow rise.
The lampswitch controller lost connection/stopped working sometime after
10pm. Jon Brinkmann called to advise power-cycling the network connections
in the lamps controller box. After doing this a few times we regained lamp
control and temps for the structure and air. Perhaps this is the same
issue that has happened the last few nights. No time was lost since we
were being pummeled by winds anyway.
 2nd Half Observing Specialist: J.Dembicky
Rain started about 01:30, things didn't improve for the remainder of the
night.  I spent the time training Dave and updating some web pages (obs
spec. schedules). Called it a night at 04:45 with the humidity at 100%.
