                  ------------- ACTIVITY LOG --------------
 1st half Observing Specialist: B.Ketzeback
 Clear skies, light winds and good seeing all of first half. During checkout
 I discovered that the Lower Right and Upper Left Enclosure Louvers did not
 open in automatic mode. I was able to open them in manual however they behaved
 in a unusual fashion. I reported the problem to Mark Klaene who in turn
 inspected them and told me it would be looked into further on Monday.
 2nd half Observing Specialist: R.McMillan
 Clear for a few hours, then thin high clouds and a jump in humidity,
 but it never reached the point of the last few nights.  Seeing was
 improved to a little over 1 arcsec.  We had two crashes of the
 slitviewer ICC, one which was timed so that it cost about 5 minutes
 of time and one which didn't cost any observing time.
