- Abstract:We present a detailed analysis of a partial eruption of a sigmoid filament lying along the polarity inversion line of the small active region NOAA 12734. The filament eruption was associated with a C1.3 flare and subsequent large-scale coronal disturbances. The active region exhibited a sigmoidal magnetic structure,disobeyed the hemispherical helicity rule,and showed sustained magnetic emergence and cancellation prior to the flare. Our analysis suggests that magnetic reconnection of highly twisted helical flux ropes under the confinement of overlying magnetic fields is likely responsible for the observed partial eruption of the filament.
