Recurrent flare/CME events from an emerging flux region View all abstracts by submitter

Nariaki Nitta   Submitted: 2001-08-28 12:35

We report on six recurrent `halo' coronal mass ejections (CMEs) that occurred (in November 2000) during a 60-hour period in clear association with major flares in an active region on the solar disk. The region was undergoing dynamic restructuring due to flux emergence. The flares were not long-decay events (LDEs) in terms of soft X-ray light curves and morphologies, although, in the impulsive phase, they produced ejections in soft X-rays that are characteristic of CMEs. We do not detect global changes in EUV and X-ray full-disk images prior to these flares. We suggest that emerging magnetic flux in the core of an active region may be responsible for the occurrence of such repeated flare/CME events.
