(* means a trouble report has been issued or appended to)
The telescope was not opened tonight, due to poor weather, and also
due to significant accumulation of snow on the enclosure.  There is a
possibility of more snowfall Wednesday night.
The scheduled observers were myself for PU01, and Paul Mason for NM13.
