(Times will be given in GMT on day 305. In general
times are rough, not precise.)

PLAN
Continue running under P24b.
At 305:16:24:43 we will pick up P24c, which includes the TOO
at SN 1999em.
P24b is expected to finish the ACIS post-belt CTI measurement, 
and do OBSID 1457, LMC X-1 with ACIS-S.


EVENTS
Status at LOS, 305:08:29, was as follows:
       PCAD MODE              =       NPNT
       CONTROL LAW FLAG       =       NPNT
       Stars:                 =          5 
       FIDS                   =          0 
       RA                     =     83.820 deg
       DEC                    =     -5.414 deg
       ROLL                   =     67.627 deg
       Format                 =          2
       OBSID                  =      62330

       SIM FA                 =       -467
       SIM TSC                =     -99616 (HRC-S)
       HETG                   =        OUT (81.0 deg)
       LETG                   =        OUT (81.0 deg)
        HRC-S HV is ON
        EPHIN:         A-Leak =   0.2320 mu-a
                       B-Leak =   0.0360 mu-a  

Next Comm, 18:30--20:00


NOTES/ISSUES/PROBLEMS
The quicklook image of Sirius B, OBSID 1421, did not
show an obvious dispersed spectrum. However, check of 
the L0 housekeeping showed that the low energy grating
was inserted at 301:21:18, and retracted at 302:04:35,
as planned.
(Information is in telf057549385N000_1_eng0.fits file, 
in /dsops/current/PROCESSING/SCCF_33_991029/cat_obs1421/run.)

Other images included 1400,1401,1403, and 1404 with 2REJ1032+532
imaged at various offsets on HRC-I. OBSIDs 1397,1398,1399, and
1402 should also be part of that sequence, presumeably not
yet processed.

OBSID 515 of ABELL 370, observed 295:01:03:38, seems to have
a diagonal "shading" over one corner.  The image is labelled 
"ACIS-I", but the observation was actually a Faint mode imaging with ACIS-S.

OBSID 1407 of G21.5-0.9 shows multiple images as if the 
LETG were inserted. But the housekeeping telemetry clearly shows LETG
retracted.

Observations of Rapid Burster, 678,  PKS2155-304, 337,
and E0102-72.3, OBSID 1410, look okay.

Items from 9am standup meeting.
	Over the weekend, 9 contacts, 13 dumps (problems with 
DSS-61, Madrid).  Dedicated efforts enabled creating, 
reviewing, and loading the TOO target, SN 1999em, ready to be
observed at 22:37 tonight.  K. Gage has injured his hand, P. Levitt
is taking over building of P25.  It is going extremely smoothly
(so far). 

Look Aheads:  Partial Lunar Eclipse on Nov 8, in P25.
	      Leonid encounter on 17 Nov, in P27, need finalization
of plans by Friday. (Look direction, operation of instruments?, TRW
analysis of encounter probability and static discharge effects).
	      There will be a followup observation of the TOO target
in P25 or P26.
