Supra-arcade Downflows - Wikipedia
Supra-arcade downflows (SADs) are sunward-traveling plasma voids that are sometimes observed in the Sun’s outer atmosphere, or corona, during solar flares.In solar physics, an “arcade” refers to a bundle of coronal loops, and the prefix “supra” indicates that the downflows appear above flare arcades. ...
