Observing Summary:

A really good night, with clear skies and excellent seeing.
We are making a lot of progress on this run, which is to measure
the frequency of chromospherically active M stars in young
star clusters.

A few times each night the telescope jumps in position and
guiding is lost for a while.  No trouble report on this issue.
