An Analysis Of The Geomagnetic Storm In Local Coordinates And Time

GEOMAGNETISM PALAEOMAGNETISM & MAGNETOSTRATIGRAPHY P4 - 01 AN ANALYSIS OF THE GEOMAGNETIC STORM IN LOCAL COORDINATES AND TIME B. Srebrov I. Cholakov Geophysical Institute Bulgarian Academy Sofia Bulgaria Introduction The geomagnetic storm is caused as is known by the interaction between an interplanetary disturbed structure formed in interplanetary space and the magnetosphere. This structure is formed by solar events such as Coronal Mass Ejections ( CMEs). On the ground the variations of the geomagnetic field during the storm dependent on the Earth surface coordinates and the local time. The local variations of the geomagnetic field during the geomagnetic storm are
