(* means a trouble report has been issued or appended to)
The telescope was not opened due to clouds, dust, and a little snow.
We had high wind accompanied by a dust "event" late in the afternoon.
The wind died down during the evening hours and we later had some
light snow (no accumulation).
The observers were myself for PU01, Asantha Cooray for UC06, and Gyula
Szokoly for JH03.
