   The enclosure was opened briefly tonight, and I do mean briefly.  We
were going to open and put the imager on.  We got as far as setting the
altitude fiducial coming out of stow when the dust counts went back over
the limit.  So we were open from about 03:45 until 04:00.  Other than that
we were closed due to high winds and/or high dust.
