Fig. 2From: The dynamics of geomagnetic substorms with the WINDMI modelEvent 06:26 UT 22 February 2006: In the bottom panel, substorm onset time from auroral observations is depicted with the red-dotted line. The WINDMI model output is compared to the AL and SML indices. The top panel shows the solar wind input measured by the ACE satellite and propagated to the nose of the magnetosphereBack to article page
