                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J.Dembicky
 Started the cooling fans around 16:00.  Opened the enclosure/telescope at
 17:50 under clear skies.
 The 1st half observer gave us a last minute  instrument change and
 filter setup for SPIcam, so they ate all the time required to
 set the instrument up, this started at 17:10.  They were also required to
 end their program at 23:45 so that DIS could be re-mounted in time for
 the 2nd half observer.
 Things ran smoothly for the first half of the night with excellent
 seeing.
 2nd Half Observing Specialist: R.McMillan
 Second half had mostly good seeing (0.6-1.1 arcsec), except for a
 brief period of rapid temperature changes.  The skies were mostly
 clear except for some very thin cirrus in the later morning.  There
 were a few strange occurrences including an unexplained rotator jump,
 but none of these oddities cost data or time.
                 ------- OBSERVER COMMENTS -------
P.Szkody (UW11): This was an excellent night -- many great spectra.
