A space weather related index that denotes a formally determined value from the daily, mean 3-hourly equivalent amplitude of magnetic activity from a planetary network of 11 Northern and 2 Southern Hemisphere magnetic observatories. It is a measure of the global scale of disturbance of the Earth's magnetic field and correlates to the breadth of the auroral oval.
