Abstract

We present rare observational signatures of interchange reconnection (IR) forced by the filament eruption inside a pseudo-streamer (PS). The PS was centered above a positive-polarity region bounded by two negative-polarity coronal holes (CHs), and thus its base contained two polarity inversion lines and a pair of loop arcades where two filaments were harbored. In white-light coronagraph data from two different views, it showed up as a fan-shaped structure consisting of fine rays and a coronal streamer. Followed by a two-ribbon flare and a coronal mass ejection, one of the filaments and its overlying arcade erupted away from the nearby CH and flew over the other arcade to interact with the PS's remote CH. As a result, distinct ribbon-like remote brightenings formed along the remote CH boundary and were. connected to the positive-polarity flare ribbon by a loop system, but the nearby open-field region largely remained. unchanged. except that compact brightenings and a following small coronal dimming appeared close to one end of the erupted filament. In combination with the coronal magnetic configuration that derived from the potential-field source-surface model, these observations can be interpreted as follows: the erupting field was first deflected and guided by the nearby CH's open field. and then reconnected with the oppositely oriented open field of the remote CH, during which both the closed field bridging the erupted filament and the remoter CH's open field were transported in the opposite direction. The observations thus supported the idea that PSs provide favorable environments for IR to take place and remote brightenings along their CH boundaries represent a credible IR signature on the solar surface.
