Analysis of the Regional Ionospheric Disturbance Index During Geomagnetic Storm in 2012

Abstract

The impacts of severe geomagnetic storms that occurred in 2012 on the emergence of largescale ionospheric anomalies in the equatorial region of Malaysia was investigated in this study. The research analyzed three significant geomagnetic storms that happened on April 24 (-120 nT), July 16 (-113 nT), and October 01 (-122 nT) of 2012, and their effects were assessed with different locations start with latitude and longitude 4˚N 99˚E,
