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

Abstract

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