Announcements
The announcement for CAT Chat was not made until 3:00 p.m.; Jan Ilavsky asked that the announcement be made on time every Monday.  Reinhard Pahl asked that at least 5 minutes elapse between the announcement and the start of CAT Chat.  The main control room will be notified of this request.

John Unik asked about the status of the booster power supply.  Patricia Fernandez replied that the problem was due to a phase difference on the power supply input.  There is a temporary fix in place that allows for injection every 12 hours (1296 mode); a permanent fix will be pursued during the shutdown.
