The cartoon

(click on the image for a larger version)

Often one meets an acronym on a cartoon legend that is vaguely familiar and possibly important, such as HFT. This stands for "Hyperbolic Flux Tube," and for a simple quadrupole configuration, it is the union of two QSLs. For reasons not clearly explained in terms of microphysics, the HFT is the likeliest place for magnetic reconnection. Note that the Archivist can make neither head nor tail of this diagram. Good luck! For a much mellower cartoon involving an HFT, please see the Janvier cartoon.
