                ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J.Barentine
 Open and cooling at 18:30.  Russet used some of the twilight time to
continue the characterization of the new Echelle guider, then handed the
telescope over at a quarter past eight.  Things ran smoothly.
 2nd Half Observing Specialist: R.McMillan
 Clear skies, no moon, excellent seeing, good pointing, no problems,
 ho-hum.  Oh, wait, there was one minor challenge; because the seeing
 was too good, we had to change the binning on the NA2 guider so that
 stars could be distinguished from cosmic rays.
