les électrons tueurs

This animation shows the positions of the satellites during the event on 25 November 2001.

During an opportune alignment that occurred during the recovery phase of a large geomagnetic storm, observations with different instruments from several different points were carried out.

A low frequency type of ULF wave, comparable to a beep every 10 minutes, was recorded continuously for many hours by the CARISMA magnetometer chain in Northern Canada. The waves were picked up by more than a dozen scientific satellites including the four ESA Cluster satellites, NASA's Polar spacecraft and four of the Geostationary Operational Environmental Satellites (GOES).
