SOHO Daily Meeting Minutes for Monday, 20 August 2001 ANNOUNCEMENTS ------------- * Submode change at 15 UT today. * The FDDI concentrator in Building 26 will be shut down on Tuesday, August 21 at 1 pm, for less than an hour. All FDDI machines in the 150.144.30 subnet will be affected. This includes all of the filers and umbra, as well as any user machines using FDDI. * Fire evacuation training will be Wednesday 22 August at 10:30am in the EOF. FOT REPORT ---------- Spacecraft Status: Nominal Spacecraft Anomalies: 232/0701 CEPAC ESU Data Request Error. Recovered autonomously after 5 minutes. Impacts TBD. 232/0914 CEPAC ESU Data Request Error. Recovered autonomously after 4 minutes. Impacts TBD. Accomplished Activities: DOY 229: VIRGO, CEPAC, RSL, Executed OCD #1542 to correct ERNE/ESU Communication Anomaly of Type 2 DOY 230: VIRGO, SWAN DOY 231: VIRGO, Noncoho Load, Flight S/W Maint. Planned Activities: VIRGO, SUMER resumes operations, Switch to Science Submode 5, Acquire new tracking star, mag = 6.9 Upcoming Operations: Sept.3 ACU/CDMU Memory Dumps Ground Anomalies: 229/1646 SH5XT1 terminal crashed. No operational impacts. 229/2000 Voice lines to Goldstone down. No direct voice communication with D16 for 14 minutes. 231/0019 SCP failure at D16 resulted in 43 minutes 34 seconds of lost TLM. All data, except 2 minutes 18 seconds, should be recoverable from the CDR. Lost command ability for 44 minutes. 231/0133 SFG failure resulted in 26 minutes 39 seconds of lost TLM from D16, and 65 minutes 32 seconds of lost TLM from D46. Data should be recoverable from the CDR. Lost command ability for 113 minutes. Delayed MDI data transition approximately 3 hours. 231/0845 Late AOS from D66. Lost 1 minute of data recoverable from the SSR. 231/0845 D66 unable to bring carrier up due to command modulation problems at the site. Commanding activities delayed 7 minutes. 232/0225 D46's initial carrier sweep for spacecraft receiver #2 failed, reason unknown. SOLAR STATUS ------------ 08/17 DOY 229 - 08/20 DOY 232 EIT daily On-Line Solar Status and observations: http://umbra.nascom.nasa.gov/eit/plan/log_form20010820.html LASCO daily On-Line Solar Status and observations: http://lasco-www.nrl.navy.mil/observations/Todays_obs.html Summary page on last week's proton storm last week: http://surfwww.mssl.ucl.ac.uk/surf/week/33_2001.html INSTRUMENT STATUS ----------------- CDS: Nominal. GIS raw dumps, AR studies watching an active region come around the east limb, quiet sun study with BBSO (SXT is also joining this study). GIS raw dumps will take precedence whenever NRT is available. SUMER: After the submode change, SUMER opens the door, powers-up detector A and waits a few hours for the instrument thermalization. From 22:00 UT today until 14:00 UT tomorrow: Full Sun HEI 584A from telescope scattered light, then Quiet Sun O VI until Lyman beta programme starts at 19:00 UT, to check the line positions on the detector. UVCS: Nominal. Star observations and synoptic. Tomorrow: polar streamer and CME observations and finishing up any remaining star observations. LASCO: Nominal. C2/C3 synoptics, C3 comets in colors observations. EIT: Nominal. 195 CME watch and synoptics. MDI: Nominal. Full disk dopplergrams and magnetograms. TRACE: Nominal. Observing on AR 9575. Tomorrow: Coordination with SUMER and possibly Sac Peak or BBSO.
