                  ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 Skies cleared by sunset.  We had a minor mounting problem with DIS that
 showed itself during checkout (The mount did not set correctly on the
 mushrooms which caused the instrument not to want to rotate properly.)
 Jon D and  I dis-mounted the instrument and then remounted it and all
 was well again.
 I adjusted focus thru the night by monitoring the guider focus and
 slitview images.
 Everything ran smoothly tonight.
