A schematic synopsis of the event. A flare occurs which is followed by a CME comprising of the leading edge or EUV wave (green) and the main CME plasmoid (blue). A funnel structure (red) within the active region is seen to host a series of rapidly propagating quasi-periodic waves or jets. A brightening is observed at the base of this structure and is interpreted as a reconnection site. After a certain delay periodic radio sparks are observed, which occur at an estimated height consistent with the leading feature of the CME, and a periodicity consistent with the fast wave period.
