Alfvén waves and Poynting flux observed simultaneously by Polar and FAST in the plasma sheet boundary layer

This paper does not have much to do with solar flares, and in fact does not even mention them, but the basic analysis of energy transport by plasma Poynting flux could well apply. All we need for the solar application is to have a couple of satellites (a solar FAST and a solar POLAR?) flying in the analogous locations above an active region, say within a few thousand km of the solar surface! Until technology makes this possible we should study papers in this genre. The satellites mentioned here are veteran magnetospheric missions. The idea is that under favorable alignment conditions, both see the same wave fields at different times. See the Fletcher-Hudson cartoon for a solar analog here.
