XRT Initial Science Plan
Principal Topics

• Flares from dynamic 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

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)
