STEREO Weekly Meeting Minutes for 2024-11-12 (Week 46) 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 45 (Nov 4-10) * On day 311 (Nov 6), during the DSS-63 support, the transmitter was declared red, due to a hardware problem. This anomaly resulted in the loss of 3.9 hours of real-time commanding and 2-way tracking data. See DR #M117464 for more information. * On day 313 (Nov 8), during the DSS-53 support, DSN successfully reverted the real-time telemetry delivery table back to original configuration to provide the MOC with only VC7 telemetry in real-time. The real-time VC6 data delivery was removed due to a MOC ground system crash caused by a memory error after four days of DSN tracks. The MOC will investigate the ground system issue. * On day 315 (Nov 10), during the DSS-36 support, the transmitter was declared red, due to a hardware problem. This anomaly resulted in the loss of 3.9 hours of real-time commanding and 2-way tracking data. See DR #C118116 for more information. * The average daily science data return for Ahead was 7.2 Gbits during this week. 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 10:25 to 14:25 UT. Week 48 (Nov 25-Dec 01) * Ahead has thirteen passes during the week, all at 720 kbps, and overall coverage is nominal. * The 172nd momentum dump is scheduled for Tuesday, November 26th, with ignition at 20:15 UT. * APL will be closed November 28th and 29th for the Thanksgiving holiday. Week 49 (Dec 02-08) * Ahead has eleven passes during the week, all at 720 kbps, and overall coverage is nominal. Week 50 (Dec 09-15) * Ahead has thirteen passes during the week, all at 720 kbps, and overall coverage is nominal. * The seventeenth battery discharge event is scheduled for Monday, December 9th, at 18:40 UT. * The 73rd SECCHI stepped calibration roll is scheduled for Friday, December 13th, at 15:50 UT. Week 51 (Dec 16-22) * Ahead has twelve passes during the week, all at 720 kbps, and overall coverage is nominal. * There is a DSN network maintenance event scheduled for Tuesday, December 17th, from 00:00 to 04:00 UT. * There is a PIT test scheduled for Thursday, December 19th, from 17:50 to 19:35 UT. * Beginning Friday, December 20th, SECCHI will be conducting special observations in conjunction with the Parker Solar Probe perihelia.
