Reality Check
Penultimate Amazing
It is quite obvious and totally settled that Alfven and others published a theory that modelled the plasma in a sunspot and the plasma-filled magnetic flux as a circuit containing a DL among other elements. The existence of the papers rather settles itThis explanation from Scott settles it for me and see Alfvens Solar Prominence Circuit "Exploding DL produces Solar Flare"
However thanks for the figure.
there! Thus the "In" in the section title does not mean "within" or "occurring inside" or have anything to do with a plasma having electrical discharges inside it.
