Summary

Closed all evening due to clouds and high winds. Used the time to
take most of the calibrations we'll need for the rest of the run.
Winds were gusting over the 20m/s limit most of the night.  We had
one brief opening but it was too cloudy to get guide or collimation
stars, and wind gusts increased once again and shut us down.  Clouds 
were mostly past us (some cirrus perhaps) a little after midnight but
winds stayed gusting above limits.  We never opened again tonight.

As per time allocation, we handed off the telescope to the PEPSI team
(J. Storm and I. Ilyn) for PFU commissioning at 2am.  Will be
coordinating this thru Sunday (PEPSI folks leave Monday).
