MDM Observatory 1.3m Telescope Observer's Report for 2005 Apr 12

Observer(s): Martin Bureau, Bettina Gerken
Institution(s): Oxford University

Instrument: Direct Imaging, f/7.6, echelle

Worked for 7:30 hours (most of the night)
Conditions were Non-Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing 1.8 arcsec, Cirrus, Winds Calm
   Mid: Seeing 1.6 arcsec, Cirrus, Winds Calm
   End: Seeing 1.4 arcsec, Cirrus, Winds Calm

Observing Summary:

Continuation of an optical imaging follow-up of the Sauron sample of
early-type galaxies. The sky was covered with fairly thick cirrus most
of the night, with a seeing almost always around 1.5-2.0 . The very
beginning and end of the night were slightly better, but we struggled
all night to find and conserve guide stars through the
clouds. Obviously, although we worked all night on and off, we had to
integrate forever on a few targets, and even then I doubt that the
data obtained are sufficient. We'll probably have to redo all objects
observed tonight to get decent S/N. Fortunately, our CCD problem of
yesterday did not occur again, so we did not waist any time due to
technical problems.
