An astonishing appeal to subphotospheric magnetic reconnection, important because it invokes this in the context of diagnostics of elemental abundance segregation, specifically in a sunspot light bridge. Who would have suspected a connection of all these dots? And more... This indeed is the first contribution to the Archive describing the first-ionization-potential (FIP) effect, and even its inverse (I-FIP) in which the segregation behaves anomalously. This is linked to flare ribbons that happen to cross a sunspot umbra.
