Movement of the Magnetopause on 8 June 2000
Top panel: z-component (Bz) of the Interplanetary Magnetic Field (IMF), displayed in blue, and the dynamic pressure (ρv2), displayed in orange, measured by the ACE spacecraft in the solar wind on 8 June 2000.
Bottom panel: magnetopause position (dark blue line) and bow shock position (bright red line) as estimated from the solar wind data displayed in the top panel. The pink area between these two borders depicts the magnetosheath, while the purple area symbolises the magnetosphere. The dashed green circle, located at 6.6 RE, depicts where many communication and weather satellites orbit the Earth.
