                ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: G.Saurage
 Clear skies, again! Amazing. Wisps of clouds now and again, but moderate
 humidity and mostly clear skies made for a decent first half.
 2nd Half Observing Specialist: R.McMillan
 Second half was mostly clear with moderate seeing and humidity
 getting down to antediluvian values.  Everything worked well except
 for a recurring error involving the writing of echelle slitviewer
 images; this occurred three or four times during second half.  The
 guide loop could be restarted immediately each time, so no time was
 lost.
