Observing Summary:

EVE ARMSTRONG'S PART (observed from dusk -> 2am)

Opened on time and got three great time series.  Sky stayed clear;
humidity low all night.

The mouse froze on me around 23:00 and I had to unplug mcgraw and 
start things up again from there.

At LST 5:00, as I was guiding, the telescope jumped about a 
minute East; lost guide star of course.
HA  2:58
RA 2:0  D -9:26.

Startled me.  And as I was already at 2 airmasses at the start,
 I considered aborting the run.  But I stuck with it without 
incident to 2.5 airmasses (30-minute run.)

Jason'll take over from here ...

My transit observations went off quite smoothly. The only problem
I had was with the seeing, which kept improving throughout the
night, despite my efforts with the heater.
