(Times will be given in GMT on day 154. In general
times are rough, not precise.)

PLAN 
Continue running May2800c load. Perform CTI measurement after ascending
from radiation belts. Perform ACIS-S measurements of the narrow line
galaxy NCG 5506, OBSID 357; and of a distant quasar subject to
gravitational lensing by a foreground cluster of galaxies, PG
1115+080, OBSID 363. The remainder of the load will be a 3/2 day
deep survey of the AXAF Southern field, OBSID 582, done with ACIS-I

Next Comms:
         154:11:10 to 13:10
         154:22:00 to 23:00
	 155:07:50 to 08:50

EVENTS
Status at AOS, 154:11:11 was as follows:

       PCAD MODE              =       NPNT
       CONTROL LAW FLAG       =       NPNT
       Stars:                 =          4

       RA                     =     37.623 deg 
       DEC                    =    -66.341 deg
       ROLL                   =    149.985 deg
       Format                 =          2
       OBSID                  =     62037 (In radiation belts)

       SIM FA                 =       -467
       SIM TSC                =     -99616 (HRC-S)
       HETG                   =        OUT (79.8 deg)
       LETG                   =        OUT (78.3 deg)
        HRC-S HV is ON 
        EPHIN:         A-Leak =  0.3760 mu-a
                       B-Leak =  0.0600 mu-a


13:10 LOS
Status essentially unchanged. Ascending through 53077 km.
ACIS Focal plane is at -119.7, and we haven't started CTI measurement
yet.

NOTES/ISSUES/PROBLEMS

Only tracking 4 stars, should be 5. The ACA error messages from loss
of track signal have caused the OBC dump overflow error again. The ACA
GSE clearly shows repeated attempts to track.

From the 9am status meeting:
	Second review of JUN0400 held yesterday. Revised products out
and a review will be held at 2pm today. This is expected to approve
products, so that the first segment of the JUN0400 load can be
uplinked at the 6 pm EDT pass today. Following approval of JUN0400,
the products for JUN1100 will be circulated this afternoon,
anticipating a review at 2pm next Monday. 
	ONLS/OFLS will be down for ~ 2-3 hours, starting 9:30am EDT
this morning, for routine monthly backups.
