Eruptive and Quasi-Eruptive Disappearing Solar Filaments and Their Relationship with Coronal Activities

Morimoto, Taro; Kurokawa, Hiroki

By measuring the 3-D velocity fields of 35 disappearing filaments (Disparition Brusques: DBs) on the solar disk, we studied the causal relationship between the motions of Hα DBs and the associated coronal phenomena. Using the derived 3-D velocity fields of the DBs, we developed a method to judge whether a DB is ejected into interplanetary space or…
