27 Sept Daily Meeting Minutes Chair: L. Allen Notes: P. Judge FOT: Nominal, no recent anomalies Ground anomalies: 270/2207 - POCC 2 string crash (30 min NRT lost) 270/2340 - Degraded data due to DSS-42 hardware problem caused 110 min loss of telemetry (recoverable) DAILY PLAN: CDS: Nominal. Supporting JOPS 17, 29, doing active sun studies SUMER: Nominal. Supporting JOPS 17, 29, today & through 28 and 29 sept. UVCS: Nominal. Some discussion of roll angles/thermal effects & yellow limits. LASCO: Nominal. EIT: Nominal. Support JOPs 17, 29. MDI: Nominal. Now operating full disk magnetogram campaign through Sunday 29. Some discussion followed on the UV-dark region to the east of the AR currently just W of sun center- rather unusual. Responding to yesterday's discussion of other spacecraft request for flare information that may correspond to other satellite's single event upsets (SEU). Discussed SoHO not designed to study flares per se. To advise people seeking information on potential satellite anomalies for low earth orbit satellites several URL's were presented for SOHO personel to recommend: 1) The best source for detecting any flare activity is by looking at GOES soft X-ray, full_Sun photometry using the Lockheed form WWW interface at: http://www.space.lockheed.com/SXT/plot_goes.html 2) The last 24 hours of GOES SXR data *updated every 5 minutes) can be found at the NOAA Space Environment Center's "Today's Space Weather" page: http://www.sec.noaa.gov/today.html 3) CELIAS's MTOF proton monitor: http://umtof.umd.edu/pm Following Joe Covington's (MDI) comments on drift of solar disk seen with MDI, Bill Thompson (CDS) showed CDS data that, though noisy, support the idea that the sun's disk has drifted slowly 2 arcseconds North in 5 months. EIT has (according to Joe Gurman) seen a shift of 4 arcsec from May to August, then returning to the earlier apparent position in September. LASCO has seen some similar qualitative evidence of a shift but exact magnitude and direction was not available to the audience. A.O.B. Jean-Phillipe Olive is organizing a bicycle ride to Mount Vernon. The bicycle ride will be on Saturday, October 5 at 10:00 am. A picnic is also planned. More details (maps, where to meet, etc.) will be provided next week. Contact Jean-Phillipe if you are interested.
