  1. Joint Planning of SOT/XRT/EIS ObservationsOutline of 90 Day Initial Observing Plans T. Shimizu, L Culhane

  2. SOT Initial Science Plan Principal Topics • Active region tracking: - Emerging AR - Mature/decaying AR - Flaring AR - Subsurface flows - MHD waves • Quiet Sun: - Network flux dynamics (Bright Points?) - Internetwork flux - Convective flow structure • Irradiance: - Activity belt - Polar regions • Prominences/Filaments - Prominence at limb/Filaments on disc - Track boundary evolution

  3. XRT Initial Science Plan Principal Topics • Flares fromdynamic AR on disk:  Follow AR across disk, flare program loaded - Deploy range of filters and FoV sizes - Flare topology and energetics • Track modest (emerging or decaying) active region on disc:  Image with large, medium and small FoVs - Structure, energetics and dynamic behaviour - AR evolution; track centre to limb? • Quiet Sun/X-ray Bright Points:  Multi-filter study of bright points - Thermal structure - Dynamics - Life-cycle statistics • Quiet Sun/coronal holes  Single filter for boundary imaging - Track boundary evolution • Quiet Sun/filament  Magnetic structure around filament - Track filament for 1-2 days

  4. EIS Initial Science Plan Principal Topics • Flare trigger and dynamics: Spatial determination of evaporation and turbulence in a flare - Characterize AR topology - Measure key structures in detail - Flare trigger response for early velocity measurement • Active region heating: Spatial determination of v, Te and ne in active region structures - High time cadence sit and stare observations; new dynamics - Observe AR global changes - Velocity measurements (± 3 km/s) • Quiet Sun and coronal hole boundary:  Correlate coronal Te, ne and v with magnetic topology - Study corona above two supergranule cells - Study corona above bright point or explosive event - Observe above a coronal hole boundary • Quiet Sun and Prominences (assume no available AR)  Spatial determination of v, Te and ne in surrounding regions -Register and follow eruption

  5. 90 Day Observing Programme Summary

  6. 90 Day Observing Programme Summary

  7. Coordination with Other Missions • Coordination with STEREO imaging should occur in first • 90 days • Coordination with TRACE and SOHO/ MDI also necessary Actions • WIKKI to be established at ISAS or MSSL • - as soon as practicable • All three Solar-B instrument teams to post brief descriptions • of their roles in above joint observing programmes (JOPs)
