                ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st shift: Russet McMillan
Clouds in the late afternoon cleared up after sunset, and the weather
was near-photometric for all of first half.  Seeing was variable with
occasional bad patches, but not so bad as the previous night.  Some
targets at higher altitude delivered seeing better than an arcsecond.
Observing went very smoothly, with the telescope and instrument both
behaving perfectly.
 Observing Specialist, 2nd shift: Camron Hastings
Things ran smoothly until 03:35 MDT when the telescope tracking had
problems. I submitted a problem report describing it. We fixed the
problem and then returned to observing for the remainder of the evening.
