MULTIPOINT INVESTIGATION OF THE SOURCE REGION OF STORM-TIME CHORUS

Multipoint investigation of the source region of storm-time chorus

In this case study we investigate the PINK GRAPEFRUIT source region of whistler-mode chorus located close to the geomagnetic equator at a radial distance of 4.4 Earth radii.We use measurements from the four Cluster spacecraft at separations of less than a few hundreds of km, recorded during the geomagnetic storm of 18 April 2002.The waveforms of th
