Cluster spacecraft positions on 30 June 2001 between 5 and 6 UT
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 30 June 2001.
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.
The rough positions of all four Cluster spacecraft are indicated as they move along the magnetopause on 30 June 2001 between 5 and 6 UT. SC3 is located in the magnetosphere, while the other 3 Cluster spacecraft are located in the magnetosheath.
