Explosive Events and the Evolution of the Photospheric Magnetic Field

Abstract

Transition region explosive events have long been suggested as direct signatures of magnetic reconnection in the solar atmosphere. In seeking further observational evidence to support this interpretation, we study the relation between explosive events and the evolution of the solar magnetic field as seen in line-of-sight photospheric magnetograms. We find that about 38% of events show changes of the magnetic structure in the photosphere at the location of an explosive event over a time period of 1 h. We also discuss potential ambiguities in the analysis of high sensitivity magnetograms.
