1st half observing specialist: Karen Gloria
	The telescope was opened at 17:45 MDT.  The seeing was very poor 2.2 -
2.8 arcsec.  The easterly wind probably had a lot to do with this. At
least there was much less dust in the air.  No problems to report other
than the poor seeing.
2nd half observing specialist: Camron Hastings
	No problems to report. Mechanical worked well. Seeing was exceedingly
poor at 2.2-3.7" for the night.
