(* means a trouble report has been issued or appended to)
The telescope was opened at 21:57 MDT.  Opening was delayed by a dust
event.  It was closed for an hour at 02:10 MDT, again due to dust.
The observers were Joni Johnson and Tom Harrison for NM08, and Paul
Mason for NM09.
			     OBSERVER COMMENTS
Joni (NM08) - "The early part of the night was marred by high dust
counts.  We opened shortly after 10 and then observed until 1 a.m.
The seeing was poor, but the conditions were adequate for the
project."
Paul (NM09) - "After one successful standard observation we had to close
due to dust. We were able to open and begin observing again
at 3:15 MST. I obtained phased resolved spectroscopy of AM Her
for about 75% of its orbital period of 3.1 hours. Everything,
besides the dusty interval, went real well."

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