Investigation on the Formation of Herringbone Structure in Type II Solar Radio Bursts

Abstract

We report detailed observation of the “herringbone” of a Type II solar radio burst that occurred on 2010 November 3rd. Data from the Space Weather Prediction Center, National Oceanic and Atmospheric Administration, e-CALLISTO, and Nançay RadioHeliograph are analyzed. We determine the brightness temperature and degree of circular polarization of the “herringbone” burst. Correlations between the physical parameters and the “herringbone” are examined. Based on the relationship, this is the first study that suggested this “herringbone” was generated through fundamental plasma.
