(* means a trouble report has been issued or appended to)
High clouds dominated the evening.  The seeing was variable.
A small set of lens data was obtained for lens 2237, but cloud cover
forced closing.  A good set was obtained for the one lens.
Rupali Chandar used DIS in high res mode for star cluster detection in
M33. Tracking through zenith, within 3deg ZD, created problems in keeping
the objects in the slit.  Clouds, and widely varying seeing, also
hampered observations.
Alan Diercks used Spicam for his observations, a tandom effort tonight
with observations being done at the MMT and APO.  Seeing was again
widely varying.  *We had difficulty in obtaining a guide star.  Stars
were in the guider field, but when the guide loop was closed, only the
central 176x176pixels are actually scanned for stars.  We had
little success with it's use tonight though, generally, stars were
available in the field.
