MDM Observatory 1.3m Telescope Observer's Report for 2005 Nov 05

Observer(s): Martin Bureau , Anne-Marie Weijmans
Institution(s): Oxford University, Leiden Univ.

Instrument: Direct Imaging, f/7.6, echelle

Worked for 10:30 hours (all night)
Conditions were Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing 1.8 arcsec, Clear, Winds Calm
   Mid: Seeing 1.5 arcsec, Clear, Winds Calm
   End: Seeing 1.5 arcsec, Clear, Winds Calm

Observing Summary:

Continuation of an optical imaging follow-up of the Sauron survey of
early-type galaxies. The whole night was cloud free and photometric,
although a few small clouds appeared on the horizon from time to time
in the second half of the night. The seeing varied from 1.5  to 2.0 
during the first half of the night, but it was almost constant at 1.5 
during the second half. We obtained R+Halpha images of a few key
Sauron objects and had another look at SN2005ew for Arlin Crotts.

We had no major technical problem, although again a few exposures
showed mild symptoms of the bias problems we experienced previously,
i.e. large sections of rows with mildly different bias levels
(051105_007, 009, 021, 037, 038). Since the offsets were quite small
(and rare), it is not a major worry.
