Observing Summary:

Observed most of the night, except for 1 hour of high humidity and
1/2 hour in which I lost control of the workstation due to an uncertain
cause.  The VNC connection might have hung, and it took several tries to
reconnect.  But more important, the type-ahead buffer got filled
with thousands of characters which then took about 1/2 hour to dump,
during which I could not use any command-line interface or terminal window.
Fortunately the telescope kept tracking. (I seem to to have more frequent
problems with VNC than anyone else.) Finally, there was constant
north-south nodding by a couple of pixels all night.  Despite the elongated 
images, useful data were obtained.
