Magnetic reconnection is a fundamental process in space, astrophysics and laboratorial plasmas that explosively converts magnetic energy into kinetic energy of charged particles. Thanks to recent spacecraft missions, e.g, Cluster, THEMIS, MMS, etc, and the development of the computing simulations, many new findings have been obtained last several years. Also, many important issues remain: the triggering mechanisms, quantitative aspects of the energy conversions, identification of the electron diffusion region, electron acceleration mechanisms, and so on. This session invites presentations on all of the aspects associated with magnetic reconnection from the spacecraft measurements, the simulations, laboratory experiments and the theoretical analysis.
