New Results on the Direct Observations of Thermal Radio Emission from a Solar Coronal Mass Ejection

We report observations of thermal emission from the frontal structure a coronal mass ejection (CME) using data obtained with Gauribidanur RAdioheliograPH (GRAPH) simultaneously at 80 MHz and 53 on 2016 May 1. The CME was due to activity far-side Sun, but near its limb. No non-thermal radio burst were noticed. This provided an opportunity observe faint CME, hence directly estimate electron density, mass, magnetic field strength plasma entrained in CME. Considering that CMEs are mostly observed only whitelight reports their characteristics also limited, rare direct independent diagnosis parameters important measurements physics.
