              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Bradley
This afternoon Misty noticed that the DIS gratings were significantly off.  The first two tries to home did not work.  Misty said she could work with it the way it was, so we took the few minutes to fix it between programs. Third time was a success.
During second half, I had an instance of ecam freezing during guiding.

It was fixed with starting the nubs and ecam init.  No time was lost.  This happened again a little bit later, but did NOT halt the guider images.
Overall the night was clear with good seeing.
