SOHO Daily Meeting Minutes for Monday, 18 December 2000 ANNOUNCEMENTS ------------- * Switching to telemetry submode 6 at about 18 UT today. FOT REPORT ---------- Spacecraft Status: Nominal Spacecraft Anomalies: None Accomplished Activities: 350: VIRGO, SWAN, RSL, New control star, mag = 4.55 Executed OCD #1453 - CELIAS TSTOL Commanding 351: VIRGO 352: VIRGO, Noncoho load, Flight S/W Maint. Planned Activities: VIRGO, Submode switch (5 to 6) ~1800 UTC Upcoming Operations: 1/2/01 ACU/CDMU Memory Dumps Ground Anomalies: 350/1623 Invalid clock correlation output. 350/2024 Command corrupted between D16 and the spacecraft, delaying NRT activities 6 minutes as 8 CDS commands properly retransmitted. 352/0630 Command activities on D66 delayed 38 minutes due to exciter and CPA failures. Lost 2 minutes of recoverable TLM. Lost 5 hours and 5 minutes of range data. Lost 38 minutes of potential MDI high rate data. 353/0406 Degraded TLM at D46 due to errors received in their receivers and TGC. 40 minutes of VC4 data was redumped from the SSR, reducing the total amount of MDI high rate data collected. Lost a total of 1 minute of unrecoverable realtime TLM. 353/1103 String #4, workstation #2, crashed causing operations to fail over to String #5 as primary. SOLAR STATUS ------------ EIT daily On-Line Solar Status and observations: http://umbra.nascom.nasa.gov/eit/plan/log_form20001218.html LASCO daily On-Line Solar Status and observations: http://lasco-www.nrl.navy.mil/observations/2000/obs20001218.html INSTRUMENT STATUS ----------------- CDS: Nominal. Polar monitoring study today and 24-hour blinker study with EIT and MDI Tuesday. SUMER: Nominal, closing door at 16 UT today. UVCS: Nominal. Study with Ulysses at South Pole begins at 16 UT today, 24-hour synoptics tomorrow. UVCS will continue with this pattern of a day of Ulysses South Pole observations followed by a day of 24-hour synoptics. LASCO: Nominal. C2 and C3 synoptics. Supporting UVCS/Ulysses with C2 pB in orange filter at 6 hr cadence. EIT: Nominal. 195 CME watch and synoptics Monday and, solar conditions permitting, 2 hours of shutterless mode observations for blinker study on Tuesday. MDI: Nominal. Full disk magnetograms and dopplergrams Monday and high res mode for blinker study on Tuesday. On Tuesday MDI will receive high rate at 00:30-03:00 UT, 08:30-11:00 UT and 14:30-22:00 UT to support blinker study. TRACE: Nominal.
