S/C Engineering(Jeff/Mike/Rino): - OBSID corruption noted yesterday "There was a dropout of the OBSID number on 108:23:09:00 for 8 VCDs. It momentarily changed to a different, but valid OBSID. We will redump the SSR for that period of time." was the same in the second dump of this data, indicating a bit change in the onboard data. There was also another word corruption in a nearby word. There was no other indication of any S/C problems. S/C eng will continue to work this. Will be added to the anomaly list. - ACIS FP temp went up to almost -107C during day 105 perigee passage. Paul P. notified. Outbound CTI was affected. SOT(Bill): - ACE flux levels in 130-214 keV channel about 1000 and decreasing. - EPHIN levels during the last pass were well below trigger levels and the GOES HE proton data (P2,P5) analogous to EPHIN P4GM and P41GM are also lower that trigger levels and trending down. - No space weather warnings. DSOPS(Joy) - No quick looks. GOT(Ken): - All is OK. Meetings/events: - 9:30am, review TOO load and associated CAP 719. - 12pm, telecon with TRW West on momentum unloading issues - 4pm, TRW West report on SSR Roger: - Independent Annual Review went very well. Much positive feedback (3 pages worth). - Thanks to all who helped prepare material - Two recommendations made: 1) Be aware that loss of knowledge about S/C, mission, etc can occurr as mission goes on, and steps should be taken to mitigate this. 2) Ground system computer update and several major contractural changes will take place next year, and plans should be made to handle these.
