Magnetospheric Multiscale Observations of Turbulent Magnetic and Electron Velocity Fluctuations in Earth’s Magnetosheath Downstream of a Quasi-Parallel Bow Shock [STUB]

Abstract: We present statistical single-spacecraft observations of magnetic and electron velocity fluctuations in Earth’s magnetosheath, likely in the vicinity of the magnetopause, downstream of a bow shock immersed in quasi-parallel interplanetary magnetic field conditions, a situation conducive to plasma turbulence in the downstream flow. These fluctuations exhibit scale-dependent behavior, wherein histograms of their Partial Variance of Increments (PVIB or PVIV(sub e)) demonstrate highly non-Gaussia…
