 I again couldn't turn off the intermediate lights when I finished my
 checkout.  I tried turning them off via computer control but that didn't
 work either.  When I went up to the dome, to open, and pressed the
 telescope incandescent lights on, the intermediate lights turned off
 (like the switch on the observing floor was keeping the other lights
 from turning on/off).  After that everything worked fine.
 We opened and got focus and a std then the clouds and dust shut us down
 before my observer could get any useful science data.
 We finally were able to open around 04:35.
 11:02:23 dcam changed guide stars on me, I don't believe I issued this
 change.  I changed exposure time, not the guidestar.  It did this also at
 11:01:08.  This one I might have actually change from boresight to a
 field star and started the guider.
