This page is a summary of the work by Working Group 5, dedicated to predicting the southern magnetic field component of CMEs.
WG5 Statement
The presence of southward magnetic fields in ICMEs are the most important factor in producing geomagnetic storms. The challenge is that direct observations of magnetic fields near the Sun are extremely limited: currently possible only in the photosphere/chromosphere at the solar end and by in-situ observations at 1 AU. WG5 aims to understand and reconstruct the possible flux rope magnetic structure of CMEs/ICMEs from observations and models. It also aims to predict the intensity and the duration of of the Bs in ICMEs upon arriving at the Earth.
Scientific and Modeling Questions
Initiation of CMEs
- Hydrodynamic ejecta
- Analytic flux-ropes
- Blob-like structures
- Data-driven model
