No equipment or software problems were encountered.

Observing Summary:

We shut down for lighning before evening twilight and powered up
again around 7:30pm local.  First half of the night was spent
observing Leo A; second half of the night was spent observing
the Bootes field AGN monitoring.  We lost pointing during the
target switch and had to re-init at the zenith, but this was 
due to misidentification of a bright star (not a mechanical 
problem).

One weird thing was a loud humming noise coming from the dome
during one of our exposures.  It happened during only one exposure
and stopped at the exact time the exposure ended and started 
reading out.  It didn't repeat for the rest of the night, so
we couldn't track down what it might have been.
