                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 The slitviewer stopped responding around 22:21 (said it was exposing
 when it wasn't and everything was ghosted except the DS9 button).  A hub
 startNubs dcam fixed the problem
 It seemed that almost everytime I homed the dis mask wheel the next
 exposure that DIS took failed (DIS/TUI thought the shutter was open).  I
 can't say it was every time for sure, but it happened several times
 during the night as the observers changed slit masks and I homed (as
 Russet told me to help keep the masks aligned without having to
 re-create them after each wheel move) the wheel beforehand.  We lost
 about 10 mins before we caught the problem.

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