Figure 1: Van Allen Probe data during the 28–30 June 2013 storm.
From: Wave-driven butterfly distribution of Van Allen belt relativistic electrons
(a) The Dst index. (b) The interplanetary magnetic field Bz. (c) Solar wind dynamic pressure. (d) Magnetic spectral intensity of chorus and MS waves from the EMFISIS instrument on Van Allen Probe A. The black and white lines denote the lower hybrid resonance frequency flhr and 0.1fce (fce being the electron gyrofrequency). (e–h) Relativistic electron differential fluxes from the REPT instrument onboard the Van Allen Probe A as a function of L showing a rapid increase in the radial range 3.5<L<5.5 where strong chorus and MS waves occur. The light grey shading area indicates the simulation period.
