At http://phys.org/print349457357.html … the New Solar Telescope at Big Bear Solar Observatory captured a high resolution image of flowing magnetic structures know as solar flux ropes that originate in the Sun's chromosphere. Flux ropes are bundles of magnetic fields that twist and rotate together (see image at link) in the Sun's atmosphere. Haimin Wang and co-authors say energy is released in solar flares and other eruptions when magnetic field lines, with powerful underlying electric currents, are twisted beyond a critical point that can be measured by the number of turns in the twist. This is interesting, coming after Bob Johnson's talk last autumn (in Watford) and the spring meeting (just gone).
