Filament Eruption and Associated Partial Halo CME on 2001 September 17

We report the eruption of a small H-alpha filament and associated partial halo coronal OF 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.
