GEOMAGNETIC STORM

Domain	Definition
Aerospace	= magnetic storm. (references)
Physics	Strong and prolonged geomagnetic disturbances extending from the high-latitude to low-latitude regions around the globe, usually caused by a long period (several hours) of strong (10-30 nT) southward interplanetary magnetic field impinging on the magnetosphere. Manifested as a sharp decrease in the magnetic field on the ground, indicating the strengthening of the ring current in the inner magnetosphere. Recovery from a storm can last as long as a few days to a week. (references)
Solar	A worldwide disturbance of the earth's magnetic field, distinct from regular diurnal variations. Minor Geomagnetic Storm: A storm for which the Ap index was greater than 29 and less than 50. Major Geomagnetic Storm: A storm for which the Ap index was greater than 49 and less than 100. Severe Geomagnetic Storm: A storm for which the Ap index was 100 or more. Initial Phase: Of a geomagnetic storm, that period when there may be an increase of the MIDDLE-LATITUDE horizontal intensity (H). Main Phase: Of a geomagnetic storm, that period when the hori- zontal magnetic field at middle latitudes is generally decreasing. Recovery Phase: Of a geomagnetic storm, that period when the depressed northward field component returns to normal levels. (references)
