Observing Specialist: A.Shelden
Night was entirely lost to clouds, high humidity, occasional snow, and a thunder snow light show during second half.
I did some analysis on the tspec noise, an email was sent to Bill, Ed, and Joe.
Telescope parked facing South, high altitude, and heaters on.  Called it a night at 04:55.
