              ------------- ACTIVITY LOG --------------
Observing Specialist:  R.McMillan
The weather was unusable nearly all night, but just barely so.  We
started out with clouds, progressed to high winds and humidity, then
had a brief period of partly-clear skies with slightly lower winds
and humidity.  Then the wind and humidity dropped but the clouds took
over, and then we had nearby radar returns (detecting something real
according to every check I could make) for all of second half.  It
never rained at the site but apparently sprinkled quite a bit nearby.
During the brief time that we were open, seeing was quite poor,
around 3 arcsec, and the telescope was noticeably affected by
windshake.  Nevertheless, the observer got several usable spectra, so
at least the night wasn't a complete loss.
