Geomagnetic Storms Sudden Commencement (SSC)Type and Implications on the Ground at Low Latitudes

Abstract

In thisresearch, we reviewed physics of some events in solar terrestrial environment include phenomenon in the region of space between the surface of the Sun and the upper atmosphere (magnetic field) of the Earth. The matter in this region is in plasma state.The methodology adopted here is to investigate the occurrence of storm sudden commencementSSC type of storms in some time span from (2007 to 2008) via the space weather index, Disturbance in the storm time Dst index,and henceto check occurrence of pulsation continuousPc5 at low latitudes ground stationsin particular, the global mode, then eventually checking whether blackout occurred or not in local region here in Sudan. From the data being analyzed a one event of blackout was found to occur associating Global mode Pc 5 pulsations occurring as a result of SSC storm. This result show that SSC type of storms has a potential sever impact in the low latitudes regions.
