              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Bradley
Started the night with the echelle slit acting up.  Tried to troubleshoot a few things, but Joe ahd to come in to take a look at it.  He managed to get it running again, but we prepared for using dis as a backup anyway.  We lost no sky time to this problem, we were just taking cals a bit into twilight.  After that, the shutter worked reliably the rest of the evening.
The rest of the night was productive, with clear skies and pretty good seeing.
