Solar Orbiter’s multi-instrument view of a coronal mass ejection

Combining imagery from three of Solar Orbiter’s remote sensing instruments – the Extreme Ultraviolet Imager (EUI), the Metis coronagraph, and Solar Orbiter’s Heliospheric Imager (SoloHI) – provides both close-up and wide views of the evolution of a coronal mass ejection (CME) on 12-13 February 2021. CMEs are eruptions of particles from the solar atmosphere that blast out into the Solar System. This compilation starts with a view of the full Sun from EUI, with the CME circled at lower left. These images show the lower part of the Sun’s corona (atmosphere) as the CME first leaps out into space. Metis, a coronagraph, blocks the light from the solar surface (represented as the black region with no data), allowing the Sun’s fainter, outer corona to be seen. The Metis field of view captures the CME as it extends from about solar radii, followed by a smaller scale eruption possibly related with the post-CME reconfiguration of the solar corona. Finally, the movie zooms out to show SoloHI’s observations, w
