Formation of a White-Light Jet within a Quadrupolar Magnetic Configuration View all abstracts by submitter

We analyze multi-wavelength and multi-viewpoint observations of a large-scaleevent viewed on 7 April 2011 originating from an active region complex. Theactivity leads to a white-light jet being formed in the outer corona. Thetopology and evolution of the coronal structures were imaged in high resolutionusing the Atmospheric Imaging Assembly (AIA) onboard the Solar DynamicsObservatory (SDO). In addition, large field-of-view images of the corona wereobtained using the Sun Watcher using Active Pixel System detector and ImageProcessing (SWAP) telescope onboard the PRoject for Onboard Autonomy (PROBA2)microsatellite, providing evidence for the connectivity of the coronalstructures with outer coronal features that were imaged with the Large AngleSpectrometric Coronagraph (LASCO) C2 on Solar and Heliospheric Observatory(SOHO). The data-sets reveal an Eiffel-tower type jet configuration extendinginto a narrow jet in the outer corona. The event starts from the growth of adark area in the central part of the structure. The darkening was also observedin projection on the disk by the Solar TErrestrial RElations Observatory-Ahead(STEREO-A) spacecraft from a different point of view. We assume that the darkvolume in the corona descends from a coronal cavity of a flux rope that movedup higher in the corona but still failed to erupt. The quadrupolar magneticconfiguration corresponds to a saddle-like shape of the dark volume andprovides a possibility for the plasma to escape along the open field lines intothe outer corona, forming the white-light jet.
