STEREO Weekly Meeting Minutes for 2024-08-06 (Week 32) 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 31 (July 29-Aug 4) * On day 214 (Aug 1), during the DSS-55 support, turbo decoder lock was lost briefly at 11:38 UT. This anomaly resulted in the loss of 63 frames of SSR data. The MOPs team repositioned the SSR pointers during the support and recovered all the affected data. See DR #M117194 for more information. * On day 216 (Aug 3), during the DSS-43 support, the downlink was interrupted between 21:08 UT and 21:16 UT due the wrong receiver being reset during a training session at the station. This anomaly resulted in the loss of eight minutes of real-time telemetry and SSR data. The MOPs team repositioned the SSR pointers during the support and recovered all the affected data. See DR #C117985 for more information. * The average daily science data return for Ahead was 7.0 Gbits during this week. Week 32 (Aug 5-11) * Ahead has twelve passes during the week, all at 720 kbps, and overall coverage is nominal. * A DSN maintenance event occurred on Monday, August 5th. After the event it it was observed that the last two IDR files from the preceding track were missing. They will be replaced soon. * On Thursday, August 8, a DMZ internet outage is scheduled from 00:00 - 01:00 UT, due to a firewall update. All instrument teams should verify connectivity following this outage. Week 33 (Aug 12-18) * Ahead has eleven passes during the week, all at 720 kbps, and overall coverage is nominal. * The 169th momentum dump is scheduled for Tuesday, August 13th, with ignition at 13:00 UT. * On Wednesday, August 14th, a MOC IONET security scan is scheduled from 13:00 to 14:00 UT. * On Wednesday, August 14th, a DSS-65 track will be shadowing a DSS-55 track from 06:45 to 10:40 UT. Week 34 (Aug 19-25) * Ahead has nine passes during the week, all at 720 kbps, and overall coverage is nominal. Week 35 (Aug 26-Sep 1) * Ahead has nine passes during the week, all at 720 kbps, and overall coverage is nominal. * On Wednesday, August 28th, a DSN network maintenance event is scheduled from 15:00 to 23:00 UT. Week 36 (Sep 2-8) * Ahead has ten passes during the week, all at 720 kbps, and overall coverage is nominal. Week 37 (Sep 9-15) * Ahead has eleven passes during the week, all at 720 kbps, and overall coverage is nominal. * The 72nd SECCHI stepped calibration roll is scheduled for Thursday, September 12th, at 12:40 UT.
