AB: Electric fields with amplitudes to 150 mV/m and average durations of 7.5 milliseconds have been observed frequently at the magnetospheric side of the dayside magnetopause and in the near-earth tail. These fields are predominantly perpendicular to B, they are electrostatic, and they occur inside local minima in the plasma density. Some aspects of their occurrence and statistics are described.
