for "beach"; however, this is likely a misunderstanding of an 1893 article by Henri-Alexandre Deslandres where the name facular flames was suggested. In the article, Deslandres also refers to them as plages brillantes, meaning bright regions, which became the more commonly used term.

Description

Classically, plage have been defined as regions that are bright in H? and other chromospheric emission lines.
