Supra-arcade downflows

Supra-arcade downflows refer to the phenomenon observed in solar physics, particularly in the study of coronal mass ejections (CMEs) and solar flares. These downflows are part of the dynamics associated with the solar corona, the outermost layer of the sun's atmosphere. In the context of solar flares, when a significant release of energy occurs, it can create shock waves and result in the ejection of plasma and magnetic field lines.
