A high-frequency broadband type II solar radio burst by Vasanth et al. – Community of European Solar Radio Astronomers
Type II radio bursts are generally observed below 400 MHz with narrow, slow-drifting fundamental and/or harmonic bands. Events with initial frequencies above 400 MHz are rarely reported (e.g. Pohjolainen et al. 2008). Such high-frequency type II may arise from the interaction of CMEs with surrounding dense structures in the corona, such as streamers, ray-like or…
