(* means a trouble report has been issued or appended to)
The dome was opened at 8:00pm with good conditions and 1.7arc-sec seeing.
Weather to the Northeast, a cold-front moving through, produced high
winds, dust, and eventually fog.  B. Becker was able to obtain some data
before closing due to significant dust levels.  Winds gusted to 45mph
ensuring that the dust remained a problem.  High humidity and fog
dominated after 3am.
No data was obtained for the lens monitoring program.
*The cloudcamera cannot be communicated with either by the scanner
software, or by telnet via apots1.  Power is not provided to
on-board cpu and, what I believe is an opto-isolator, is indicating a
a blown fuse.
I was able to obtain a guider image with one, bright star that was well
focused, but the new centroiding software will not accept it.  The
software reports the correct centroid but then reports that 'no stars
found', as reported on the obs2mac.
