                ------------- ACTIVITY LOG --------------
Observing Specialist: Russet McMillan
The telescope was opened late at 20:45 due to threatening weather
nearby.  Skies gradually cleared during first half, and the seeing
appeared to be moderate, although it was hard to be certain since we
were doing many targets at high airmass.  Despite some concerns about
the stability of the tertiary, the telescope was pointing well while
SPIcam was in use, and we saw no evidence of flopping from the mirror.
The scheduled observer for PU08 was extremely ill, so I volunteered to
do some service observing at short notice.  As on previous nights,
problems with the GRIM Mac caused interruptions in the script
observing.  GRIM users are advised to plan around such interruptions
by making their scripts as modular as possible.
The telescope was closed at 04:00 due to rising dust.
