Grotrian (famous for the so-called Grotrian diagrams of atomic energy levels) noticed (3) a possible transition whose wavelength matches the red coronal line (637.4 nm).

Heating mechanisms of the solar corona

Electron capture is thus associated with the activation of a highly ionized species which then emits the well known coronal lines. Unlike the SSM, light need not be invoked to excite these highly ionized species.
