Project Analysing CME deflections

Objectives

Objective of the project

Study the influence of the coronal environment in the early development ofCMEs to better understand the deviation between the source region(filament or active region) and the non-radial direction of propagation ofCME (i.e. deflection).

Preliminary results

The magnetic environment affects the dynamics of the CME:

CHsStreamers

The evolution of the prominence morphology may or may notaccompany deviation of the CME.

Work in Progress:

We are analyzing 10 more deflection events to understand relatedconditioning factors.
