Magnetic regions on the Sun viewed by Solar Orbiter

This image shows a magnetogram taken with the Polarimetric and Helioseismic Imager (PHI) High Resolution Telescope on ESA’s Solar Orbiter on 28 May 2020. It spans an area of approximately 200 000 km x 200 000 km on the solar surface. The small structures seen are magnetic regions of both north and south polarities, some of which have sizes of a few 1000 km.

Solar Orbiter is a space mission of international collaboration between ESA and NASA.
