Observing Summary:

Telescope tracking stopped many times when observing at HA = -5.5
to -4.5.  Then some rapid (~10 Hz) E-W oscillation was observed,
similar to what occurred in the early days of the new TCS.  I did
get a few good hours, until the humidity rose.  Closed at 2:30am.
Gave up at 3:00am as humidity is still rising.
