Radio-rich solar eruptive events

We report on the analysis of a large number of solar eruptive events that p roduced radio emission in the dekameter-hectometric (DH) radio window (1-14 MHz), newly opened by the Wind/WAVES experiment. The distinguishing charac teristics of coronal mass ejections (CMEs) associated with the DH type II r adio bursts are larger-than-average width and speed. Flares of all sizes (X -ray importance B to X) occurring at all longitudes were associated with th e DH type II bursts and CMEs. We found a global enhancement in EUV over an area much larger than the flaring active region in the beginning many event s. A comparison between the 'Shock Associated' events and microwave bursts shows that at least half of the events do not have temporal relation. A maj ority of the DH type II bursts were associated with IP shocks and kilometri c type II bursts. In particular, we found a very close relationship between the kilometric type II bursts and the IP shocks.
