Scientific paper

We study the global development of the 2007 May 19 event and investigate the origin and the escape of the energetic electrons responsible for the interplanetary bursts and for the solar energetic particle event. The data analysis combines radio spectral and imaging observations with STEREO EUV observations. We also use the direction-finding capabilities on the Wind/Waves radio instrument. Electron acceleration and injections into the interplanetary medium occur with some delay after the flare. It is shown that they are related to the expansion of the coronal mass ejection and of the extreme ultraviolet imager wave. There are two accelerations at two different locations in the corona which correspond to two different electron trajectories in the interplanetary medium.
