 Observing Specialist: R.McMillan
 Another lovely photometric night.  Seeing was subarcsecond at times,
 through the right filters, but mostly between 1 and 1.5 arcsec.  I
 was worried about tracking early on when a few test images were
 elongated in the azimuth direction, but later long exposures (10-25
 minutes, all with guiding) came out just fine.  The only hard part
 was keeping up with the focus when the air warmed several degrees in
 the middle of the night.

     Note: the wind was coming from the azimuth listed.  The convention
     used is north=0 degrees, east=90 degrees.  The dust count is
     particles > 1u per 0.1 cubic feet.
