   End: Seeing 1.1 arcsec, Clear, Winds Calm

Observing Summary:

A good night all in all!

At our first target (dec = +66), we experienced a lot of jiggle
and sometimes large oscillations in the N/S direction.  The images
often look terrible, but experiments show we can recover 
accurate differential photometry.  We were looking into a 
10 mph wind.

Our second target (dec = -02) gave us no problems.  Good seeing,
steady tracking and guiding.

The guider was giving the telescope a relatively constant nudge
to the N at both targets, which suggests something about the N/S
balance or preload is amiss.

The data from this run will be extremely good, though the extra
motion problems will complicate the reduction.  I want to thank
Bob and Tony and Richard Treffers for their dedication and 
extra effort.

The only casualty of the night was to the mouse population, 
which is reduced by at least four.
