                              THE PLAN:
                              =========
Since there is cloudiness, we will do spectroscopy, if we can.
                              SYNOPSIS:
                              =========
We started off with cart 8/plate 300 and cart 3/plate 311 tonight, as last
night.  If the clouds allow we will try and do this plate.  At midnight,
there was a lot of thick nasty cloud, so we were forced to wait.  At 01:30,
the clouds came on quite heavily from the west (where the wind was coming
from), and killed off any on-sky opportunities for the rest of
the night.
         GENERAL COMMENTS (see Problems below for details):
         ==================================================
Because of the heavy cloud cover, DIMM was not open, and we had to wait out
the clouds.
We closed up for good at 05:00.
endNight 51644 -doSpectro ran without problems.  The tapes were put in the
recycle bin.

                           ================
Mainly cloudy to the W at midnight.  Winds at to 15 mph, with gusts to 25.
Dust at 2000 so we have to watch it.
Similar to last night, we did not get a clear continuous 20 minutes from 01:00
on.
