(* means a trouble report has been issued or appended to)
1st half observing specialist: Loomis, Deglman
The telescope was opened at 17:10 under a lot of cirrus.  Kevin
Krisciunas observed for UW02, with SPIcam, and Michael Strauss,
Xiaohui Fan, and Jill Knapp observed for PU04 with DIS.
2nd half observing specialist: McMillan
Second half remained very cirrusy, but never so cloudy that we needed
to close.  The windspeed nearly reached the limit shortly after
midnight, then quieted down a little afterward.
The PI for UC09 was not aware that he had time, so there was some
delay before he was ready to observe.  He decided to use the echelle
rather than DIS, and we started out with service observing until his
preparations were complete.  He plans to use DIS tomorrow as well, and
I advised him to submit a swap form.
