              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Found a problem with DIS bay2 gratings/turret tonight.  This delayed DIS cals until almost the end of twilight.  I chalked the time up to equipment loss as it was eventually discovered as an equipment problem that needed to be fixed.
Rest of the night was clear but we had poor seeing, winds out of the east. The seeing improved later in the 2nd half.
DIS left mounted as Carol was taking cals at the end of the night.  I didn't move GIFS back in its park position as I wasn't sure if they were going to want it mounted during the daytime or not.  I will move it back in the afternoon.
