Solar flares represent an explosive release of energy on time scales of minutes to hours, in the form of high-energetic particles, plasma heating and flows. CMEs are huge amounts of magnetized plasma expelled into the interplanetary space (where they are called ICMEs) with hundreds to thousands of km/s, occasionally heading towards Earth. Both events are frequently associated with large-scale large-amplitude waves and shocks in the solar atmosphere, so-called EIT (EUV) and Moreton waves. The talk will focus on recent resarch results about the CME/flare feedback relation and association of such eruptive phenomena to coronal waves observed with STEREO.
