(* means a trouble report has been issued or appended to)
1st half observing specialist: Karen Gloria
The telescope wasn't opened this evening, due to clouds, high humidity
and generally unsettled weather.  The observers were Patrick Crotty for
Adler (UC08) and Gordon Richards for UC01.
Craig found the cause of last night's failure of the DIS PC to send
images to disk.  It was an obscure networking problem, which he is
fairly confident is now fixed.  In addition, an improvement was made to
the mc.  Users are now warned with an error message if the DIS PC
fails to send an image to disk.  Previously, the mc would just rename
the old scratch image with the new image name with no warning that
something was amiss.
2nd half observing specialist: Russet McMillan
High humidity persisted during second half, with occasional snow.
