Disabled) P41GM = 0.0 LT 8.47 A-leak = 1.0200 mu-a B-leak = 0.4320 mu-a Descending through 110541 km. ACIS focal plane temperature -119.7. NOTES/ISSUES/PROBLEMS From the 9am status meeting: Loads were stopped by P4 RADMON trigger of SCS107 at 336:17:31. Ran CAP 820 to disable momentum auto-unloading. Loaded DEC0303A to perform a maneuver to a favorable momentum, and valve temperature, orientation. DEC0403A products are out this morning, for a load review at 2pm EST this afternoon. This will resume the observing program as previously planned in DEC0103B upon egress from perigee tomorrow, IF the radiation environment permits. Radiation will be discussed at the 2pm load review, but the GO-NOGO decision is expected at a telecon 7:20am EST tomorrow, at start of the comm at which DEC0403 would be uplinked. DEC0803 products are delayed to incorporate a TOO to observe X-ray jets in GRS 1915+105, and also due to the need for continuity with the eventual replan. Expected out tomorrow. GOT will be doing router work today -- admin network expected to be down for about 20 minutes. Notice will be sent in advance. The installation of ONLS 9.3.4 scheduled for tomorrow must be delayed (again) due to the heavy demands of mission planning caused by the radiation event replans. There will be a requirements review for the HRC-as-RADMON-trigger software patch, at 10am in the action room. 405 244 5060 1165#.
