Fig. 5From: Estimating the solar wind conditions during an extreme geomagnetic storm: a case study of the event that occurred on March 13–14, 1989Solar wind parameters obtained from the ACE satellite and the Dst index during the storm that occurred on November 20–21, 2003. Top panel: intensity of the magnetic field. Second panel: geocentric solar magnetospheric (GSM)-Y component of the magnetic field. Third panel: GSM-Z component of the magnetic field. Fourth panel: solar wind speed. Fifth panel: number density of the solar wind. Sixth panel: dawn to dusk solar wind electric field (VBs). Bottom panel: Dst indexBack to article page
