ANALYSIS OF DISTURBANCE STORM TIME INDICES

ABSTRACT

One of the energy sinks during Solar Wind Magnetosphere Ionosphere (SW-M-I) system is ring current injection rate, and this energy rate depends on the Disturbance Storm Time (DST). In this paper data from World Data Centre Kyoto (WDC) obtained at International Service for Geomagnetic Indices (ISGI) was used in this studies and International Association for Geomagnetism and Aeronomy (IAGA-2002) format was adopted in the analysis. Results obtained shows that the DST indices varies with time which indicate that proper monitoring of geomagnetic indices is required for accurate energy estimates.
