              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
A photometric night throughout, but with moedate to poor seeing.  I didn't record the focus info correctly, but seeing was 1.7-2.2 arcsec on various measurements, with occasional flares to worse values.
Engineering tasks accomplished: new dcam shutter checkout; dcam alignment; DIS slitviewer vs spectrograph focus check; DIS throughput on four stars; new dcam maskfiles; Shack-Hartmann measurements and collimation adjustment; pointing model; observations with ARCTIC.
