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.
