Observing Summary:

Varying cirrus from sunset until power interruptions and thickening cirrus shut us down
at ~3 AM.  Power interruption killed the Internet, which was my primary link to the
MDM manuals.  So both I and the observer at the 1.3m had trouble figuring out
what to do if the main power was having brief interruptions.  The paper manuals
in the observing rooms are scattered and some pages note that they are
out-of-date. Conservatively, we both decided to follow the lightning shut down
procedure, just in case the power troubles worsened.  No internet, couldn't submit a
timely night report.
