Sun is a source of heating, light and releases massive amounts of ionized particles (plasma) in all directions of interplanetary (IP) space; it causes an active source for geomagnetic activities, which in turn affects the navigation systems. A class of these activities happened sudden variation in the global magnetic field namely, geomagnetic sudden commencement (SC) and can be detected by magnetometers on the ground and in space. The current study concerns with the SC measurements obtained from a number of satellites distributed around the earth to have a global feature of the magnetic field at different local times and different altitudes.
