   Once again we were shut out by the weather.  High winds, high dust, and
ever thickening clouds kept us closed.  The large shield of clouds coming
up from Northern Mexico made it ... err  clear by about 23:00 that we would
not be able to open tonight.
   Charlie did some testing of MCP mod's by running the rotator around.
   Once it was obvious the clouds were here to stay, Connie started her
work on the imager.  She expects to be finished tonight.  So far things
have gone well.
   I noticed the display on the counterweight control panel for weight
number 2 was reading zero, despite the fact that the weight appeared to be
in the same position as all the others ( about 690 ).  The cable to the
string pot seemed to be connected.  I'm not sure exactly what work was done
in and around the controller today, but something may have gotten bumped
during the work on the VME crate.  It's probably something minor, but we do
need it operational with all the upcomming work with spectrographs,
cartridges, etc.
