Study of CME structure and evolution deduced from ULYSSES/HI-SCALE energetic particle observations Original Research Article

In this work, we study the anisotropy characteristics of solar energetic electron (E > 53 keV) fluxes observed by the ULYSSES/HI-SCALE instrument during the passage of a well-identified Coronal Mass Ejection. On the basis of the energetic electron observations, firm conclusions are drawn on whether the detected Coronal Mass Ejection has been detached from the solar corona or is still magnetically anchored to it.
