            ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan,C.Gray
The night started out clear but with poor seeing.  We still aren't able to
record focus data properly, but measurements were around 1.5-1.8
arcseconds.  We worked on DIS internal focus and on-sky focus until the
telescope was cool, then we refined the collimation from the previous
night.  About when that was done we had some clouds that prevented any
work for a while, then we finished up with a small pointing model which
was a real struggled even through thinner clouds.
