              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
The moths are back.  We had a whole bunch in the library tonight.
During checkout, I moved the gratings to set 2 and noticed that the turret Detent was at 99.  I homed it twice to get it >1400.
The Optidew outside dew point was reading wrong compared to all the other weather dew point sensors on site.
04:43UT (22:43) Internet seems to have went down on us.  It came back up on it's own around 23:25.  ARCSAT was taking an image sequence so even though they were disconnected they never lost any sky time.  My 3.5m observer image did finish around 22:50, so I counted time loss due to Equipment for the down time.  I called him as soon as the internet came back up.  Internet was slow but usable for the remainder of the night.  IT guys will be investigating in the day.
