A standard 2D reconnection cartoon, a la CSHKP, but with perhaps a record-setting number of 2D complexities. The large-scale structures seen in early Hα observations were described in terms such as "nimbus", "flash", "cloud"; please read this paper for a connection to these historical things. We should not forget the Hα flare observers, because they became us!
