              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
DIS Bay 2 red grating is getting sticky when calibrating again.  I moved it the amout it wanted, -4 steps, and it only moved about -1 step.  I didn't bother moving it again as it tends to just want to jump back and forth and it was within about 3-4 steps of being centered.  This is a known issue with this particular grating motor but seems to be a little worse as of late.
High humidity and clouds kept us closed all night.
ION controllers were fine this morning when I shut the telescope down at 05:15.
