Tsurutani, B., Shibata, K., Akasofu, S., and Oka, M., "A two-step scenario for both solar flares and magnetospheric substorms: Short duration energy storage," EPS 61, 555 (2009).
Over the eons (well, centuries) there has been speculation about the relationship between the electrodynamics of solar flares and of geomagnetic storms. At first glace there are some points of similarity, and so it has been natural to search for common physical processes. Unfortunately solar flares can only be observed by remote-sensing tools (astronomy), whereas magnetic storms can also be detected in situ. The cartoon portrayed here again seeks analogies. An earlier cartoon in this genre is that of Obayashi but really the basic ideas are far from new even with his work. In any case the earlier cartoon invokes electric currents, whereas the present cartoon does not, so this may be a small step backwards. However we appreciate the colors in the cartoon.
