The first X-class flare of Cycle 24, SOL2011-02-15, attracted a great deal of attention. This cartoon is in a familiar style favored by those who relish coronal fields more complex than simple bipoles. This kind of thinking goes way back in history, at least to Bratenahl & Bauml in 1976, if not to the grandfather of flare cartoons, Giovanelli. The alternative to this kind of geometry is the ever-popular CSHKP picture espoused by Moore & Labonte. There could be room on the Sun for both pictures!
This paper sought to explain the EIT wave without reference to a freely-running blast wave as invoked by Uchida. The quasi-perpendicular expansion into the streamer field evokes the EOVSA observations of SOL2017-09-10 (qv).
