EVENTS

Status at LOS, 295:05:48, was as follows:
       PCAD MODE              =       NPNT
       CONTROL LAW FLAG       =       NPNT
       Stars:                 =          4 
       FIDS                   =          3 
       RA                     =     40.003 deg
       DEC                    =     -1.601 deg
       ROLL                   =     47.677 deg
       Format                 =          2
       OBSID                  =        515

       SIM FA                 =       -467
       SIM TSC                =      75624 (ACIS-S)
       HETG                   =        OUT (81.0 deg)
       LETG                   =        OUT (81.3 deg)
        HRC HV is OFF
        EPHIN:         A-Leak =   0.1800 mu-a
                       B-Leak =   0.0280 mu-a  

Next Comm, 13:00--14:00

Status at AOS, unchanged from above. 

14:00 LOS. 
Status unchanged except:
			 A-Leak =  0.1760 mu-a
			 B-Leak =  0.0280 mu-a


NOTES/ISSUES/PROBLEMS
The ODB has implemented yesterday's ECR to 
change the HRC-I and HRC-S focus set points in the 
CHARACTERISTICS file, to   -716,    -1048, respectively.

From 9am ops meeting:
P23 products review for 2pm today. The end of p22e has been
modified, and will be uploaded tonight. P23 is actually only
partially complete, through next Tuesday.
The P007 database is (almost) ready to install.  Limits have
been verified. It remains to verify scripts.

Note that the scheduled time of the ACIS pre-belt
CTI measurement is    CAL-ER 1999:299:13:01:18.6.  This should
be the target time for their "squeegee" mode diagnostic.

One of the stars is not being tracked. It is too near the 
edge of the field of view. The aca backstop program reported:
">>>> WARNING! Angle Too Large. [ 6]" for this star.

Quick look data:
	Data System ops has been off the air for 36 hours while
disks were being upgraded. Processing has now resumed.
