The march 22 flare is one of the strongest flare in this solar maximum. This move was made by me and used in a public talk in Science Park in NY-NJ. The talk was for warning for the how harmful a solar flare could be. In science,  what this event interested me was that the time profile was surprisingly short. Why it should not? Well, A thumb rule is that  a large flare has everything: large-area, complex magnetic fields, and long-duration of radiation. I related this event to a case of spontaneous reconnection, based on the magnetic field configuration, EUV, radio Ha images. Thus it becomes a paper that addresses the MHD aspect of the solar flare.
