                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Clean skies. Night went well except for one occurance where the shutter
 on DIS stuck shut after the user changed masks (slits). Homing the shutter
 did the trick and no real time was lost. No other troubles.
