                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 Skies cleared during twilight but clouded up just as twilight ended
 (21:00) which prevented me from opening.
 A DIS flat didn't appear to work tonight (see below for when the
 exposures were taken, perhaps a filetype was set wrong by the observer?)
 It seemed to fix itself so no PR was reported.
 02:53:31 bias started
 02:54:16 bias read
 02:54:33 200s flat started
 02:57:51 flat read (bad flat Q3NM04/flat.0007)
 02:58:35 200s flat started
 02:59:24 flat read (aborted, bad flat Q3NM04/flat.0008)
 03:01:51 200s flat started
 03:05:13 flat read (good flat Q3NM04/flat.0009)
 136-212 (22:56-23:11) DISslit image was bad.  Then is suddenly came back
 in image 213 (Observer just paused their exposure).
 DIS slitviewer locked up several times tonight (see times below).  A hub
 startNubs dcam fixed the problem each time.
 02:05 DISslit locked up (needed to be kicked with a hub startNubs dcam)
 02:14
 02:23
 User reported the internet connection being very slow for him, maybe part
 of the DIS slit problem.
 02:57
 We didn't have any more problems with the slitviewer after this time.
 No problems otherwise, and the slitviewer problems seemed to clear
 itself (no PR's submitted and no real time was lost).

     used is north=0 degrees, east=90 degrees.  The dust count is
     particles > 1u per 0.1 cubic feet.
