                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Az Vel Scales: Was 574.0 Measured:  583.0, changed to 580.0
 Another night of mostly clear skies. Seeing was moderate to poor and
 a bit variable first half of the night. Second half it was moderate to
 good. Pointing after switching ports tonight was about the same as was
 seen last evening. However after the tilt correction the observer
 had no difficulties with pointing and complimented the tracking since
 she was doing long unguided exposures with few needed  manual corrections
 while observing Venus. The dis-slitviewer hung twice tonight but
 recovery was quick in both instances.
