The "emergence" of solar magnetic flux is how solar physicists describe the
increase of B at the photosphere,
as observed via Zeeman-split line profiles.
This obviously complicated subject comes replete with other jargon, such as
"flux submergence," "flux cancellation,"
"bipole,""Ellermann Bomb" (EB),
"moustache," "arch filament system,"
"moving magnetic feature" (MMF),
and so forth.
It is not for nothing that we hear the
"dermatology" smear!
The newly-emerged flux can quickly lead to flares, on a time scale of a day
or so in a major active region.
This elegant and well-organized cartoon sketches some of the problems
in the presently ill-understood
physics here, which in the modern era has begun the hard task of incorporating
3D structures with ion-neutral electrodynamics.
