Radio Bursts Associated with Flare and Ejecta in the 13 July 2004 Event [PDF]
, 2008 We investigate coronal transients associated with a GOES M6.7 class flare and a coronal mass ejection (CME) on 13 July 2004. During the rising phase of the flare, a filament eruption, loop expansion, a Moreton wave, and an ejecta were observed.
