                ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J.Barentine
 Opened to cool at 19:00 under clear skies and generally light winds.
Closed at 19:30 to allow Paula to take some cals with the dome dark.  Open
again just before 20:00 to continue cooling while waiting for the sky to
darken.  First half was quiet, seeing varying between aout 0.9-1.4 arcsec.
 2nd Half Observing Specialist: R.McMillan
 This night was again quite peaceful, although less idyllic than the
 previous two nights.  We had clear skies and subarcsecond seeing for
 the first few hours of second half, then some cirrus moved in and
 seeing puffed up to 2 arcseconds shortly before 03:00 MDT.  The
 seeing later settled down again, but the clouds stuck around.
 Everything worked well except for a crash of the guider Mac around
 04:45, requiring a power-cycle to reboot it.
 I finished up with some more testing and characterization of the new
 echelle slitviewer.
