                               ACTIVITY LOG
(* means a trouble report has been issued or appended to)
The telescope was opened briefly from 19:00 to 19:25.  It looked like
the sky was clearing, but it clouded over again.  Only the Sacramento
Mountains were cloud covered.  We had a light dusting of snow during
the night.  The sky finally started to clear during twilight, although
it was still to humid to open.
The scheduled observers were Jeff Secker and a student (I didn't get
your name) for WS02, myself for PU01 and Ed Turner with Yashushi Suto,
Toru Yamada, and Ichi Tanaka for PU03.
