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,
with seeing hovering around 1.5  all night, with small periods of
better or worse seeing. We completed our long exposures on the Sauron
sample and even had time for a few  extras . We also monitored a
number of variable sources for Arlin Crotts: 5 AGNs and SN2005ew in
VRI.

We had no major technical problem, although a couple of exposures
showed mild symptoms of the bias problems we experienced two days ago,
i.e. large sections of rows with mildly different bias levels
(051104_027, 051104_066). Since the offsets were now quite small (and
rare), it is not a major worry.
