                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 DISslit was hung tonight, Fritz restarted it's icc and that fixed the
 problem (dcamera process was locked out).  No time lost since DIS was on
 2nd half.
 No problems otherwise during the night.  I tweaked focus throughout the
 night.
