On Dec. 2, 1991 Yohkoh/SXT obtained a unique sequence of high quality X-ray images of what appeared to be a plasmoid ejection and two-ribbon flare, viewed in cross-section on the Solar limb. We will show a movie displaying the preflare plasmoid formation, the eruption of the plasmoid followed by the onset of the flare, and finally what appears to be the formation of postflare loops in a quadrupole type field configuration. We have modelled this sequence of events with a simple Martens-Kuin circuit approach, approximating the plasmoid/filament as a line current, added to a background field consisting of three line-dipoles. Overlays of the X-ray movie with the calculated magnetic field morphology show excellent agreement, and thus lend further credibility to the two-ribbon flare scenario developed by Carmichael, Sturrock, Hirayama and many others thereafter.
