(Times will be given in GMT on day 026. In general
times are rough, not precise.)

PLAN
Continue running load JAN2300b. Observe OBSID 877, the radio quiet quasar 
BRI 1033-0327, and OBSID 323, the elliptical galaxy NGC4636, both with
ACIS-S. That will be followed by the prebelt safing actions and ACIS
CTI measurements.

Next Comms:
        026:14:05 to 15:45
        026:22:00 to 00:00
	027:06:00 to 08:00
	027:13:15 to 15:15
	027:18:45 to 20:30
	028:02:50 to 04:20
	028:13:10 to 14:30
	028:22:00 to 00:00

	Descending through 132531 km.

15:45 LOS
Status essentially unchanged (target position differs a few arcsec due
to dither). 

NOTES/ISSUES/PROBLEMS
Notes from 9am status meeting.
	Uplinked another load segment, only one more to go to complete
JAN2300b.  Products for the load JAN3000 out this am, for a review
to be held at 3pm today. Feb0600 load has no stars for one OR, that
one may just be dumped from that week.
	JPL installed a new comm system on January 7. They
subsequently had some problems with the sizes and timeliness of file
transfers from their remote stations, leading to the data delivery
glitches we have been experiencing. These are believed to have all
been solved as of Jan 20. :)
	Dan Muleady will be giving a briefing on the revised safing
system (actually, on the complete safing system I believe), in the
first floor auditorium, 9am to noon on Friday, Jan 28. All are
welcome. Note change in location from that announced in L185 shift report.

No quick look images today. :(
