Filament Eruption and Associated Partial Halo CME on 2001 September 17

Abstract

We report the eruption of a small $H_{\alpha}$ filament and associated partial halo coronal mass ejection (CME) occurring in NOAA AR 9616. Accompanied by a M1.5 flare, the filament quickly erupted, a remote coronal dimming region far away from the eruption site was formed above quiet-sun area, and then a long $H_{\alpha}$ surge developed from the flare site. During the eruption, remote $H_{\alpha}$ and EUV brightenings appeared near the dimming, along the dimming boundary in EUV and in its interior in $H_{\alpha}$, leaving behind EUV loops connecting the eruption source region and the remote EUV brightenings. Finnally, as a definite indication of the CME, a huge dark loop appeared to span the eruption region. These observations indicate that a much larger-scale rearrangement of the corona magnetic fields, eventually represented by the CME, was involved in the eruption of the small filament.To search for other articles by the author(s) go to: http://adsabs.harvard.edu/abstract_service.html
