Coronal mass ejections in relation with radio burst related geomagnetic storms and sun spot

Abstract In this paper we have selected radio burst related geomagnetic storms of magnitude ≤-90nT from 1997-2012 (i.e. solar cycle 23&24). For this period we have found 42 geomagnetic storms and most of the geomagnetic storms are associated with halo and partial halo coronal mass ejections (CMEs) with association rate 67.57% and 32.43% respectively. Statistical analyses are performed to examine Read More …
