Coronal mass ejections are thought to originate from the over accumulation of magnetic helicity (Rust & Kumar, 1994). While recent studies revealed the incompetence of CME associated active regions in creating enough helicity for CMEs (Nindos, Zhang, & Zhang, 2003 and references therein), we have tried to seek, on the other hand, if particular helicity patterns are retained by CME-associated active regions.
