                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 We had some last minute instrumnent changes to the 1st program tonight
 because of a problem with the Echelle.  The night started out with cirrus
 but then thinned out at sunset.  We had waves of passing cirrus clouds
 until around 3AM when it just got too thick to observe the 2nd programs
 objects.  We threw in the towel around 5AM when it was doubtful from the
 satellite image that we would open for the remainder of the night.
 The 2nd program gave a few minutes to the 1st program so that they could
 finish their observations.  Otherwise a pretty uneventful evening.
