Solar wind evolution - assessment for multi-viewpoint instruments

Short Description

Starting point / motivation

High-speed solar wind streams emanating from coronal holes may cause strong geomagnetic effects at Earth, especially during times of solar minimum activity.

Contents and goals

We will perform investigations on the evolution of coronal holes, their underlying magnetic field, and consequences at Earth using the unprecedented 360° view of three satellites around the Sun.

This enables us for the first time, to track coronal holes as they evolve, and to follow them over several rotations. The temporal and spatial evolutions of the solar wind are important parameters, which let us better understand and forecast geomagnetic storms.
