Abstract:
We present here a selection of electromagnetic ion cyclotron (EMIC) wave activity observed using the recently launched Magnetospheric Multiscale (MMS) satellite constellation and the Van Allen Probes. The equatorial orbital configurations of these missions are ideal for observation of the theoretical source region of EMIC waves. From the launch of MMS in early March of 2015, both missions have observed a similar region of MLT across the night side, though the differences in apogee allow a larger span of coverage in L. The spatial configuration of the MMS constellation will allow for full wave number solutions to an unprecedented degree of accuracy. This, coupled with the temporal separation of the Van Allen Probes, will allow us to define the size and persistence of observed wave activity regions, and directly measure the propagation characteristics of these waves.
