Quasi-periodic Fast-mode Wave Trains within a Global EUV Wave and Sequential Transverse Oscillations Detected by SDO/AIA

Here we have a rather glorious cartoon, replete with mechanisms involved in coronal developments associated with an eruptive flare. The artist, Wei Liu, has brought color and excitement into several of the Archive's items. The "global EUV wave" would be identifiable with the Moreton wave. The Archivist likes the information being gleaned about the lateral development of the disturbance. Uchida's original description of global waves used the WKB approximation to describe the bending of the global wave front towards the chromosphere, thus neatly offering a theory for the Moreton wave and for the phenomenon of "winking filaments". These represent the chromospheric skirt of the global coronal wave. Here these wonderful new observations show much more about the processes involved, including especially a quasi-periodic property.
