A modern cartoon showing that there is still life in a 2D representation
of magnetic reconnection, here tackling the popular "flux cancellation
nanoflare" concept again.
The 3D geometry, properly discussed in the paper, presumably resembles
the more stylish portrayal in an
Ellermann Bomb cartoon in the
Archive.
In such a physical picture, converging flows force the field to reconnect.
Why is this not a continuous process, where and when does it occur, etc.;
these questions all remain open since we don't understand the microphysics.
Thus there seems to be no physics here, and yet observationally "flux
cancellation" really does lead to
jetsbright points, filament eruptions,
flares, etc., as well as the Ellermann Bombs.
