We focus on electron acceleration events that occur during relatively quiet periods, excluding large transients such as flares or coronal mass ejections. We build a database of such events observed by near-Earth spacecraft such as ACE, WIND and STEREO and shortlist only those which can plausibly be linked to acceleration episodes in the solar corona. The electrons detected at the Earth during such episodes presumably represent a fraction of the population that was accelerated in the corona. By calculating the power carried by the energetic electron population observed at the Earth, we hope to obtain an estimate of the power involved in the coronal acceleration episode. Such an estimate directly yields the energy contained in the accelerated electrons, without an appeal to the radiation generated by them or subsequent plasma heating. |
