Abstract

For this study, we have to consider radio bursts (RB) related geomagnetic storms of magnitude ≤-90nT for the period 1997-2012 with coronal mass ejections (CMEs). For this period we have found the total number of geomagnetic storms is 42. Out of these 37 geomagnetic storms are found to be associated with coronal mass ejections (CMEs). Majority of geomagnetic storms are related to halo coronal mass ejections. Out of 37 geomagnetic storms 25 geomagnetic storms are related to the halo coronal mass ejections and 12 geomagnetic storms are found to be associated with partial halo coronal mass ejection. Again all the geomagnetic storms are associated with Solar X-ray flares of different categories. Majority of the geomagnetic storms are associated with M class Solar X-ray flares. We find the weak positive correlation with correlation coefficient 0.28 between the magnitude of radio bursts related geomagnetic storms and speed of associated CMEs.
