Abstract:
In this study we analyzed two halo CMEs observed by the LASCO/SOHO coronagraph on 18 November 2003 and 3 April 2010. On-disk, EUV signatures were recorded by EIT/SOHO, both CMEs being associated with erupting filaments. The events were detected in-situ by ACE and they both produced geomagnetic storms when interacting with the Earth magnetic field, approximately 2 days after their eruption from the Sun. A detailed study and comparison of these events using multispacecraft observations will be presented and discussed.
