                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 Filled TSPEC Aux tank this afternoon.  Not sure if anybody had done it in a while (nothing was in
the fill log) and Bill requested a fill last Friday.
We had a system off to our west during twilight that moved off to our southwest.  Around 23:00 we
had an approaching system from our northeast.  At 00:30 I decided that the system was close enough
to be a potential threat.  While moving the telescope to park it, the humidity shot over the limit
and winds picked up.
The winds picked up during the 2nd half as the system slowly moved by us.  Wind and humidity kept
us closed.  We also were completely overcast for a good portion of the 2nd half.  We threw in the
towel at 04:35.
