SOHO Daily Meeting Minutes for Friday, 16 November 2001 ANNOUNCEMENTS ------------- * All OCD's for the weekend must be in by noon today * X-panel heater changes continue. There will be no NRT today from 19:00-19:10 UT. * ICAL is today at 16 UT * Submode change is today at 19:10 UT. * There will be security scans on Monday starting after 11:15 am local time. Please turn off ipfilter, portsentry, zonealarm, or whatever other personal firewall type software you might be running so that the scan can be done without long timeout delays. Note that we're still looking into this matter. FOT REPORT ---------- Spacecraft Status: Nominal Spacecraft Anomalies: 317/1756 SUMER DPU hung and the instrument's power was cycled at the LCL level per OCD #1583. Impacts TBD. 319/0112 Experiment off-pointing monitoring executed when FPSS anomaly flag triggered. Cause unknown at this time; investigation pending. Accomplished Activities: 317 VIRGO, RSL, 26 Meter equipment test with D16 318 VIRGO, Roll Maneuver activities 319 Completion of Roll Maneuver activities, VIRGO, Nom. HGA Table Planned Activities: VIRGO, CELIAS, RSL New control star, mag = 5.90 SUMER stops observations Switch to DHSS Science Submode 6 (~1910 UTC) Upcoming Operations: Nov 3-19: X-panel Heater Turn-Off Ground Anomalies: 318/1029 Big pipe failed between Madrid and JPL. Lost 3 minutes 21 seconds of recoverable data. Delayed roll maneuver preparation activities 3 minutes 21 seconds. 318/1934 Degraded telemetry due to RFI between 1934 and 2229. Any lost data is unrecoverable. 318/2230 Late carrier up at D46, cause unidentified. Delayed roll maneuver activities 14 minutes. 319/0013 Experiment off-pointing monitoring triggered as the AOCS pointing flags were not cleared prior to enabling the COBS function. 319/0622 Y-axis hydraulics failure at D66 caused AOS to be 4 minutes late. 319/1904 Corrupted command due to low uplink power on D27 delayed NRT commanding 3 minutes 26 seconds. 319/2110 Degraded telemetry due to RFI received from 2110 to 2141 (31 minutes). Any lost data is unrecoverable. SOLAR STATUS ------------ 11/15 DOY 319 - 11/16 DOY 320 EIT daily On-Line Solar Status and observations: http://umbra.nascom.nasa.gov/eit/plan/log_form20011116.html LASCO daily On-Line Solar Status and observations: http://lasco-www.nrl.navy.mil/observations/2001/Todays_obs.html INSTRUMENT STATUS ----------------- CDS: Nominal. CDS will do ICAL 1 today; support UVCS/Ulysses observations on Saturday; and CME watch on AR 9690 on Sunday. CDS will also do other usual weekend studies. SUMER: Nominal. ICAL today. Powering down at 18:30 UT. UVCS: Nominal. UVCS will observe at 340 degrees for Ulysses campaign through the weekend. Mini synoptic today and Sunday and long synoptic on Saturday. LASCO: Nominal. C2/C3 synoptics. EIT: Nominal. 195 Angstrom CME watch and synoptics. ICAL today. MDI: Nominal. Full disk magnetograms and dopplergrams. Then MDI will switch to high res mode for a line profile study to be run today and Saturday. TRACE: Nominal. Continued to observe AR 9690 in UV. Then ran some flats. Then switched to AR 9697 (coordinating with MDI in high res) AOB: --- Today is Klaus Wilhelm's last day here for SUMER operations since next year he will be retiring. It has been great working with you Klaus and we send our best wishes with you. Werner Curdt will be taking over as the PI for SUMER when Klaus retires.
