                               ACTIVITY LOG
(* means a trouble report has been issued or appended to)
The telescope was opened at 01:45 MDT and closed at 02:45 MDT.
Opening was delayed by clouds and then by high dust count.  Of course,
the sky began to cloud up again the moment the telescope was opened.
So, we weren't open very long.
The observer was Gerhardt Meurer (JH01).  Camron hastings and I were
the telescope operators.
