STEREO Weekly Meeting Minutes for 2007-10-16 (Week 42) - corrected ANNOUNCEMENTS ------------- * None. INSTRUMENT AND SPACECRAFT STATUS -------------------------------- * All subsystems on both spacecraft are nominal, except that the Ahead spececraft is currently operating on IMU #2. * SECCHI is experiencing dropouts causing a tiny amount of data loss - the cause is being investigated DISCUSSION AND OPERATIONS CONSTRAINTS ------------------------------------- Week 41 * Average daily downlink was 7.2 gigabits on Ahead and 7.4 gigabits on Behind. Week 42 * STEREO-Behind didn't have a command uplink on Station 55, an extra track was received. - M Oct 15 (288) Week 43 * The SWAVES 90/270 degree rolls are tentatively scheduled for Monday, day 295. A decision will be by F Oct 19 (292). *The Behind spacecraft roll to 180 degrees is cancelled. * The first anniversary of the STEREO launch will be celebrated at APL on Thursday, Oct 25. * STEREO-Ahead is predicted to pass through the Leonids shower on Sunday, Oct 28 from 08:00-16:00 UT. No action will be taken on the spacecraft. Instrument teams plan to take preventive measures similar to those used for momentum dumps. PLASTIC will turn off their entrance system. SECCHI is considering closing some of the SCIP doors. Week 44 * Nothing unusual Week 45 * STEREO-Ahead has a momentum dump @ 19:30 UT (day 321) COORDINATED OBSERVATIONS ------------------------ ------------------------------------------------------------------------------- Scheduled activities for Week 41: M Oct 08 (281) T Oct 09 (282) W Oct 10 (283) T Oct 11 (284) F Oct 12 (285) S Oct 13 (286) S Oct 14 (287) ------------------------------------------------------------------------------- Scheduled activities for Week 42: M Oct 15 (288) T Oct 16 (289) W Oct 17 (290) T Oct 18 (291) F Oct 19 (292) S Oct 20 (293) S Oct 21 (294) * Intercalibration JOP ICAL01 Oct 15-19 ------------------------------------------------------------------------------- Scheduled activities for Week 43: M Oct 22 (295) SWAVES 90/270 degree rolls, Ahead 04:00, Behind 07:00 will be loaded F Oct 19 (292).
