               -------------- Activity Log --------------
1st Half Observing Specialist: K.Gloria
     The telescope was opened at 19:30 MDT.  I was not able to get
twilight flats for UW02, however, due to work on a *focus problem with
DIS. Aside from that and some high clouds UW02 went well.  I observed
for that program with Kevin Krisciunas looking on from UW.  I had to
close at 21:30, due to dust.
     Tom Williams and Paul Mason were on site to observe for NM06.
The dust closure continued for the remainder of the first half of the
night.
2nd Half Observing Specialist: N.C.Hastings
	We were unable to open second half due to dust counts at first and
then opaque cloud cover later.

used is north=0 degrees, east=90 degrees. The dust count is for the
particles > 1 micron per 0.1 cu.ft.
