1st half observing specialist: Karen Gloria
	I observed for PU01, and the seeing was pretty awful 1.7-2.0 arcsec. We
had high winds from the SW all day.  This put some dust into the air.
The dust counter on the tower was reading about half what the
dust counter in the enclosure was reading.
2nd half observing specialist: Camron Hastings
	I took over in time to switch to the TNO project. Seeing was again bad,
1.2-1.8". It seemed that the guider was also causing very odd
corrections. Very large, and they seemed to introduce more error, so we
quit using it. During the early night, when DIS was still on, I noticed
that even with the guider the object required more corrections than
normal to keep it on the slit. The weather remained photometric all
night and all equipment otherwise functioned normally. I also switched
the format of the observing time around to match the account sheets we
have to fill out in addition every night. This makes it easier at a
glance to transcribe numbers and not misplace them in the wrong column.

	-- I could not access Marmot for the weather data --
		It was clear with moderate winds all night...
note: the wind was coming from the azimuth listed.  The convention
used is north=0 degrees, east=90 degrees. The dust count is for the
particles > 1 micron per 0.1 cu.ft.
