The meeting will span four full days. Each day will consist of an interdisciplinary plenary session, and contributed oral and poster presentations. The four interdisciplinary plenary sessions will include sessions of interest across Heliophysics: Space Weather, Heliophysics Applied to Stellar-Planet Systems, Ion-Neutral Coupling Throughout the Heliophysical System, and Magnetic Reconnection in Space Plasmas. There will also be many sessions devoted to other topics, both interdisciplinary and more narrowly focused. Some of these sessions will be led by organizers, in the conventional “AGU style”, while others will be created by the Scientific Organizing Committee after the abstracts have been submitted (SPD style).
