                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: C.Hastings
 I opened the dome under sunny skies at 16:30 MST to allow cooling and
 some sky exposures with the echelle. Misty logged in to work on DIS
 cals and all systems seemed to run well, now under cirrus skies.
 2nd Half Observing Specialist: R. McMillan
 Second half had moderate seeing with cirrus and a few heavier clouds,
 never thick enough to prevent observations.  We lost just a few
 minutes when the slitviewer exposures were apparently too short (1
 second), causing Remark to freeze up.  When we stuck to longer
 exposures, the problem didn't recur.  Everything else went smoothly.
