(* means a trouble report has been issued or appended to)
Observing Specialist: McMillan
Rain, rain, beautiful rain -- a little over half an inch.
The telescope was not opened during first half due to thunderstorms
and high humidity, but the closure was in a good cause, since we
needed the moisture.  The humidity and clouds remained troublesome for
a while, but we were able to open at 04:00 and get a little data for
both UC05 and PU05, with surprisingly good seeing considering that the
primary mirror had been 10 degrees C warmer than the air just over an
hour before.
While we were closed during first half, tests of the echelle
calibration mirrors produced a few repeats of last night's error
messages, which were traced to the hardware.  Calibration images also
had some trouble writing to disk legibly due to long comments, a known
bug.  While telescope was open, the echelle worked perfectly.
