PLAN ---- Continue running load FEB0501c. Finish OBSID 1928 of VELA X-1 with ACIS-S/HETG, and perform CTI measurements surrounding perigee passage.

ACIS focal plane temperature -119.5. 1609 LOS NOTES/ISSUES/PROBLEMS From the 9am status meeting: Over the weekend, 9 supports, all data recovered. Three load segments uplinked. Onboard load good through day 40:2000. Schedule is fixed for FEB12. There were errors in command loads, the fix is known, products out today or early tomorrow for a load review tomorrow. Data on SSR B has been recovered, but there were two spurious readouts of the OBSID, so CAP 696 has been written to dump this data once again to try to isolate the source of the error. Solar proton flux is very low at about 30, and steady.
