than that containing the reconnection electric field. Electrons bounce along the closed field lines earthward of the X line continue to be accelerated by this electric field at every return to the region. The second configuration is represented by high magnetic field fluctuations surrounding a main reconnection X line. The thermal component in the second configuration tends to be much hotter than that in the first configuration. The statistical results also indicate that coherent magnetic islands, although effective in accelerating electrons, are not the dominant process for energizing electrons to suprathermal energies in the magnetotail. We discuss the potential analogy of these observations to solar flare electron energization.
