A Filament-Associated Halo Coronal Mass Ejection

Zhang, Jun; Wang, Jingxiu; Nitta, Nariaki

There are only a few observations published so far that show the initiation of a coronal mass ejection (CME) and illustrate the magnetic changes in the surface origin of a CME. Any attempt to connect a CME with its local solar activities is meaningful. In this paper we present a clear instance of a halo CME initiation. A careful analysis of magnet…
