                ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st shift: Russet McMillan
The weather was near-photometric, aside from some haze or dust moving
overhead part of the time.  Seeing was worse than recent nights, with
delivered FWHM in the range 1.5-2.0 arcseconds.  The wind was
moderately high, and a few examples of image motion were probably
caused by windshake too fast for the guider to compensate.  Otherwise,
the telescope and instruments behaved perfectly.
 Observing Specialist, 2nd shift: Noel Camron Hastings
Seeing deteriorated quickly as I came on. No telescope or instrument
problems reported. I switched to SPIcam at 01:10 without incident.
Seeing improved near morning.
