This is another nice cartoon that isn't one of your comprehensive
end-to-end flare cartoons, such as one of the well-developed but
perhaps boring CSHKP examples. The problem tackled here is the
electrodynamics of flux emergence. How does a subphotospheric
fibril field map onto a coronal space-filling field with net currents,
as needed for flare energy storage? This is a complicated subject
and there are debates
(e.g. Melrose vs.
Parker) on the nature of
the physics involved. Meanwhile we can all enjoy the cartoon.
