Coordinating Solar and Inner Heliosphere Research for the International Heliophysical Year

The Solar/Inner Heliosphere Working Group, led by Joan Burkepile, Leonard Strachan, and Nancy Crooker, is focused on defining key science topics for observation and modeling campaigns related to the solar minimum irradiance, coronal magnetic fields, and cosmic ray modulation. Priorities include detailed planning for observation campaigns, modeling tasks, and fostering international collaboration. The group seeks volunteers for leadership roles and aims to incorporate new missions like SDO and STEREO to enhance our understanding of solar-helio phenomena.

  1. International Heliophysical Year Coordinators for Solar and Inner Heliosphere Working Group: Joan Burkepile (HAO) Leonard Strachan (CfA) Nancy Crooker (BU)

  2. Solar/Inner Heliosphere W.G. Working Group Participants (from NSO mtg):

  3. Solar/Inner Heliosphere W.G. New S/IH Working Group Participants:

  4. Solar/Inner Heliosphere W.G. • Near Term Goals: • Select science topics and subgroups for possible observing campaigns • Select science topics and subgroups for possible analysis and modeling • Intermediate Goals: • Work out detailed plans for each campaign • Work out details for modeling tasks

  5. Solar/Inner Heliosphere W.G. Suggested Campaign Topics from NSO meeting: • Variation of solar minimum irradiance (cycle to cycle) • Off-limb coronal magnetic field measurements • Electron temperature measurements from electron scattered disk spectrum • Quiescent filament observations • Plage brightness & flux rope initiation • Far-side imaging of corona and magnetic fields • Chromospheric magnetic field measurements (SOLIS)

  6. Solar/Inner Heliosphere W.G. Suggested Campaign Topics (continued): • Generation of subsurface magnetic fields • Study of how subsurface flows structure the corona • Relationship of cosmic ray modulation to CMEs • Characterization of CME shocks and relationship to solar energetic particle production • H-alpha observations of sunspots, filaments & flares • Cross-cutting themes of universal processes in different solar/heliospheric environments

  7. Solar/Inner Heliosphere W.G. Links to other IHY Working Groups: • Cosmic Rays/Outer Heliosphere WG • Solar cycle variations … • Ionospheres/Magnetospheres WG • Coronal/solar wind disturbances … • Climate and Earth Atmosphere WG • Solar irradiance variations …

  8. Solar/Inner Heliosphere W.G. Issues: • Volunteers needed for: • Observation Campaign Leads • Modeling/Analysis Leads • Mission/Instrument Leads • Institutional Leads • International Contacts for Solar/Heliosphere • Incorporate new missions: Stereo, Solar-B, SDO • Possible loss of some NASA missions!
