[6.07] Long Lasting Type II Radio Bursts

Plasma frequencies starting in the decameter-hectametric (DH) regime and continuing into the kilometric (km) regime correspond to approximately to the entire Sun-Earth distance. Accordingly, we consider Type II radio bursts observed by the WAVES experiment on the WIND spacecraft that are observed from the DH to the km regimes and their association with white-light coronal mass ejections (CMEs). We find that approximately 80% of these events are associated with metric Type II bursts observed on Earth. We also consider correlations of DH/km Type II's with sunspot numbers and other cyclical measures of solar activity, and properties of CMEs associated with DH/km Type II bursts.
