                              ACTIVITY LOG
(* means a trouble report has been issued or appended to)
Observing Specialists: Deglman, Bergeron
Opened at 17:10 under a slightly cloudy sky.  While filling the IRSC, a
weird sound was heard apparently coming from the stopped 3.5m dome.  Upon
investigation nothing obvious was found.  Evening twilight sky flats were
obtained for the Fabry-Perot.  Some problems with intermittent clouds
during focusing.  Closed from 20:15 to 22:15 for shutter repair of the
Fabry-Perot.  While observing in the north, the seeing from the guider was
virtually the same as the DIMM measurements until about 01:00.  When the
seeing deteriorated, DIMM was much higher than the NA2 guider.  Closed at
02:55 due to high wind gusts.  Reopened at 03:20.  Reclosed at 04:00 due
to high winds and clouds.  The cloud camera was lagging about one half
hour as first noticed around 03:50.  This explained why a guide star
"inexplicably" disappeared just after reopening then reslewing to the same
object with the same rotation.  The DIMM was closed early (nothing to
record).
