                              ACTIVITY LOG
(* means a trouble report has been issued or appended to)
1st half observing specialist: Dan Long
   The enclosure was opened tonight at 16:50.  Skies were clear most of the
first half of the night.  A few wisps were noticed in cloud cam images
around 22:45.
   The net was much better behaved tonight.  I think the switch to MCI out
of NMSU was a marked improvement.
   Seeing tonight was much improved over the last couple of nights.  During
the lens monitoring run seeing was between .8 and 1.0 arcseconds.  It
increased to around 1.2 arcseconds after 21:00.
*  There was one odd problem with SPICAM tonight.  It started complaining
that there wasn't enough room on /export/images to write a frame.  A check
of available disk space showed 4 GB free.  It became chronic enough that we
switched to using dryrot to write images, which worked fine.  Below is the
response to an "object" command when it wouldn't write to tycho followed by
an excerpt of a df -k command.
not enough space left on disk (1441792  1 micron per 0.1 cu. ft.
                             TELESCOPE STATUS
Primary, secondary, and tertiary mirrors in place and collimated.
Primary support system operational.  Mirror ventilation system in
place.  Telescope drives operational.  Current Remark version: 2.42a.
Current guide software version: GIm Ctrlv3.0b15.
