| Abstraksi | : | One of the space weather phenomena is geomagnetic storms. Geomagnetic storms were caused by the entry of fast solar wind due to Coronal Mass Ejection in conjunction with the Interplanetary Magnetic Field (IMF )Bz. that leads to the south. Conditions of solar wind component along southward of IMF Bz before geomagnetic storms can determine the formation of geomagnetic storms. In addition, through the solar wind conditions and Bz component of the IMF before the geomagnetic storm intensity of geomagnetic storms can be estimated through the model of geomagnetic storms as a function of the density of solar wind and geomagnetic storms models as a combined function of the density and speed of the solar wind. This case study used geomagnetic storm events data occurred in March 17,2013; February 19,2014; March 17,2015; and June 23,2015. The results of the study showed that the estimates of the geomagnetic storms (Dst index) based on the condition of the solar wind components before geomagnetic storms and geomagnetic storm models as a combined function of the density and velocity components of the solar wind were still quite good. However, the estimates of the geomagnetic storms using the model as a combined function of the density and velocity components of the solar wind with the average deviation of 17,6 nT (12.8%) were better than using the model of geomagnetic storms as a function of the solar wind density with the average deviation of 37.3 nT (27.6%). |
