                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan, G.Saurage
 The evening started with several hours of photometric skies and very
 good seeing.  Later we had a little wispy cirrus and some less-good
 seeing, but altogether it was an excellent night.  No problems
 except that the focus numbers were a little hard to guess, probably
 due to the large changes in temperature over the last few days.
