                ------------- ACTIVITY LOG --------------
1st half Observing Specialist: G.Saurage
Mostly clear skies at sunset. A few thin clouds now and again, but other
than that no problems. Seeing poor to moderate tonight.
2nd half Observing Specialist: R.McMillan
Second half had good seeing, but thin clouds moved in around 4 am.
The DIS slitviewer shutter gave a little bit of trouble during test
images before observing started, but had only one failure once we got
going.  Could be partly warmer weather, partly long exposures by the
observer, but we hope it's also partly the steps taken by daystaff to
keep the shutter warm.
Despite a struggle with the clouds, APOLLO got returns from three
reflectors in the morning.
