NOTES/ISSUES/PROBLEMS
From the 9am status meeting:
Ten supports over the weekend. Issues with DSS-24 transmitter
problems, but no impacts on Chandra operations. 
A few Transmitter B high power violations occured -- similar to
previous occurences and not considered as a concern.
Running on DB2 over the weekend, but will fail back to DB1 this
morning. 

Radiation Telecon:
A radiation telecon following the status meeting agreed to attempt to
restart the observing program by commanding loads at the pass at 
256:0345. We will pick up the original SEP1205B schedule with obsid
6220 at 256:08:11, and try to schedule the postponed Crab Nebula obsid
5555 prior to that time. Products due out later today for a late
afternoon or early evening load review.
