Magnetic reconnection as a driver of chromospheric surges

Abstract

The basal structure of a surge precisely on the limb has been photographed with 1″-resolution in the core and wings of Hα. The dynamics observed in the fine structures are consistent in general with reconnection theory, but they also display flows more complicated than those predicted by 2D-reconnection models. The magnetic topology of the surrounding long-lived plage indicates that flux cancellation rather than its emergence is the key factor in promoting recurrent surges at this site.
