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).

Results
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.
