STEREO Weekly Meeting Minutes for 2024-10-15 (Week 42) ANNOUNCEMENTS ------------- * None INSTRUMENT and SPACECRAFT STATUS -------------------------------- * Ahead is operating nominally. PLASTIC is in operational mode, but with a moderately higher than normal background rate. * Four years after the initial loss of communications anomaly with the Behind observatory, NASA has directed to cease periodic recovery operations with the last support on October 17, 2018. DISCUSSION AND OPERATIONS CONSTRAINTS ------------------------------------- Week 41 (Oct 7-13) * On day 284 (Oct 10), during the DSS-25 support, turbo decoder lock was lost briefly at 15:54 UT. This anomaly resulted in the loss of 23 frames of SSR data. The MOPs team repositioned the SSR pointers during the support and recovered all the affected data. * The average daily science data return for Ahead was 7.3 Gbits during this week. Week 42 (Oct 14-20) * Ahead has ten passes during the week, all at 720 kbps, and overall coverage is nominal. * The 17th Solar Orbiter remote sensing window ends Tuesday, October 15th. * The 18th Solar Orbiter remote sensing window begins Thursday, October 17th. * On Thursday, October 17th, from 14:00-16:00 UT, DMZ and/or DSN connections may be disrupted due to a software firewall update. Instrument teams should verify connectivity following this event. Week 43 (Oct 21-27) * Ahead has twelve passes during the week, all at 720 kbps, and overall coverage is nominal. * The 171st momentum dump is scheduled for Wednesday, October 23rd, with ignition at 18:30 UT. * The 18th Solar Orbiter remote sensing window ends Saturday, October 26th. * Saturday, October 26th, is the eighteenth STEREO launch anniversary. Week 44 (Oct 28 - Nov 3) * Ahead has nine passes during the week, all at 720 kbps, and overall coverage is nominal. * An ESA Cebreros track is scheduled for Wednesday, October 30 from 01:40 to 02:20 UT. * Daylight Savings Time ends Sunday, Nov 3. Week 45 (Nov 4-10) * Ahead has ten passes during the week, all at 720 kbps, and overall coverage is nominal. * On Wednesday, November 6th, Parker Solar Probe has a Venus flyby, and Solar Orbiter will be collecting observations for a full-disk mosaic. * An ESA New Norcia track is scheduled for Thursday, November 7, from 02:45 to 03:40 UT. Week 46 (Nov 11-17) * Ahead has thirteen passes during the week, all at 720 kbps, and overall coverage is nominal. * APL will be closed on Monday, November 11 for the Veterans Day holiday. Week 47 (Nov 18-24) * Ahead has eleven passes during the week, all at 720 kbps, and overall coverage is nominal. * There is a DSN network maintenance event scheduled for Wednesday, November 20, from 10:45 to 14:25 UT.
