WebJul 3, 2024 · Recent in situ observations, however, found relativistic (more than 100 keV energies; v > 0.5 c) electrons upstream of quasi-parallel bow shocks with both a high Mach number (at Saturn) ( 5) and a low Mach number (at Earth) ( 6 ). Such electron energy exceeds even the maximum electron energy (tens of kilo–electron volts) predicted by … Webdence of the bow shock’s location and shape on Pram, MA, and MS is that the bow shock is almost always moving; it is a dynamic object. Times when it is al-most stationary are rare and therefore important for studies of the shock’s intrinsic structure. 12.2 Fast Mode Nature of Earth’s Bow Shock
