Solar Orbiter Captures the First Ever Image of a Magnetic Solar Switchback on the Sun - by spacewriter
The Metis-enabled Solar Orbiter images and data, coupled with some computer modeling of magnetic field regions on the Sun, show that switchbacks occur when open field links interact with nearby closed field lines. All the lines crowd together and eventually reconnect into stable configurations. That action releases energy and creates an S-shaped disturbance that travels out to space.
The observation of this S-shaped kink in the coronal plasma caught the attention of Daniele Telloni of the Astrophysical Observatory of Torino, Italy . It reminded Telloni of an idea by Gary Zank of the University of Alabama in Huntsville. He suggested the idea of field lines between different regions reconnecting and switching back. Zank immediately recognized what was happening after he saw the spacecraft data.
