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

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 Nancay 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.

Automated summary

This paper reports a detailed observation of a Type II solar radio burst on November 3, 2010. Data from multiple sources are analyzed, including the Space Weather Prediction Center, National Oceanic and Atmospheric Administration, e-CALLISTO, and Nancay RadioHeliograph. The brightness temperature and degree of circular polarization of the herringbone burst are determined, and correlations between the physical parameters and the herringbone are examined. Based on these findings, it is suggested that this herringbone was generated through fundamental plasma.
