Pulsating Auroral Forms and Their Association with Geomagnetic Giant Pulsations

On the night of 29/30 October 1987 a giant pulsation (Pg) was recorded on the EISCAT magnetometer cross and the U.K. Sub-Auroral Magnetometer Network (SAMNET), accompanied by a variation in auroral luminosity with an identical periodicity of 77 s. Coincident all-sky image data showed that the aurora...
