When the interplanetary magnetic field turns south compared to Earth's magnetic field (the arrow pointing below zero) geomagnetic activity will increase. The lower the arrow, the more that geomagnetic activity. | Green for low, yellow for moderate, and red for high solar wind speed. | A function of the solar wind's speed and density.
