Study of the Extensive Geomagnetic Storm with Helio- Spheric Phenomena during the Period of Solar Cycle 24

Abstract

Saket Kumar1* and PL Verma2

Geomagnetic storms are impactful space weather occurrences because they may disrupt power grids, communication systems, and spacecraft operations. The MC sheath, the leading (or front section) area of an MC, the trailing part of an MC, and collective sheath and MC regions can cause an extensive geomagnetic storm. This paper uses descriptive analysis to identify them with helio-spheric phenomena using the Disturbance Storm Time Index (Dst). Depending on the availability of data during the period of solar cycle 24, we include the four extensive geomagnetic storms allied with various solar parameters/interplanetary magnetic field components that were potentially geo-effective and occurred on "St. Patrick's Day" (17 March 2015), (23 June 2015), (20 Dec 2015), and (26 Aug 2018).
