                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 Cloudy at the start of the night which prevented me from opening, so I
 let Tom and James continue their work upstairs on APOLLO while Craig did
 his stuff with the telescope remotely (Echelle Slitviewer, DIS
 slitviewer stuff).
 Tom and James were moving the telescope to the upper and lower limits (I
 think checking clearances and installing stuff for APOLLO.  I noticed at
 01:30 that the transverse load cell seemed a little unhappy (with some
 smallish oscillations present).  I went upstairs and manually moved the
 telescope up and down, which calmed the load cell down and back to it's
 normal looking self.
 Clouds remained all night long with periods of light rain as well.  I was
 unable to open tonight so we will need to take time tommorow night to
 finish up our pointing model.
 At 04:30 I gave up, there was no chance the clouds would clear in the
 next hour long enough to get our pointing model (the moon was completely
 obscured by the clouds)

     used is north=0 degrees, east=90 degrees.  The dust count is
     particles > 1u per 0.1 cubic feet.
