                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: Russet McMillan
 The telescope was opened before sunset for cooling, but thick clouds
 prevented us even from getting focused until about half an hour after
 the end of twilight.  Intermittent clouds and variable seeing
 prevailed for the remainder of first half, making science difficult
 but not impossible.  The observer chose not to use the echelle
 autoguider, but the tracking was good and everything worked smoothly.
 2nd Half Observing Specialist: Camron Hastings
 Second half started smoothly. Cirrus moved in and out all night, hampering
throughput a little but not much. All systems ran well with semi-poor
seeing.
