AB: Large (≤ 600 mV/m) perpendicular and parallel electric fields were measured in the Earth's bow shock for the first time by the vector electric field experiment on the Polar Satellite. These fields exist on spatial scales comparable to or less than the electron skin depth (a few kilometers) and they contain parallel potentials of tens of volts and perpendicular potentials up to a kilovolt. We discuss these results in the context of electron kinetics in the shock front.
