Kinematics of a compression front associated with a Coronal Mass Ejection
Abstract
On 2014 November 1st a solar prominence eruption associated with a C2.7 class flare and a type II radio burst resulted in a fast partial halo Coronal Mass Ejection (CME). Images acquired in the extreme UV (EUV) by SDO/AIA and PROBA-2/SWAP, and in white light (WL) by SOHO/LASCO show a bright compression front expanding ahead of the CME. The main goal of this work was to infer the location and timing of the shock formation in the corona. A comparison between the starting frequency of the type II emission and the frequencies derived from the inferred coronal density distribution, allowed us to identify a region located northward of the CME as the most probable site for shock formation.
