| − | =='''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.
