Coronal Mass Ejection, Solar Flare and Interplanetary Shock Caused Geomagnetic Storms During Maxima Phase of Solar Cycle 24
Year: 2025
Type: article
Abstract: We analyse study about maxima phase of solar cycle 24, which is the mostly recently completed solar cycle, it starts at December 2008 to December 2019 duration of solar cycle is 11 year, max sunspot activity max count month at April 2014 and max count value 81.8. we discuss about Coronal mass ejections (CMEs) and Solar flare (SF), how can generate and disturbance create Earth magnetosphere? Solar flare is energetic X-ray or Solar energetic particles (SEPs) and CME contain large amount of plasma. Another solar parameter Interplanetary Shocks (IP) which can disturbed Earth’s magnetic field. In this solar cycle Dst≤ -30nT according 27 geomagnetic storms value observed, this value associated with CMEs, SF and IP shocks, 77.77% association rate between CME and geomagnetic storm, where partial halo CME (51.85%) and halo CME (25.92%), solar flare association rate is 84.61% and M-class (22.22%). C-class (37.03%) and X-class (18.51%) respectively but remaining 22.22% CMEs and SF not belongs to Dst index. We examine IP shock only Fast Forward (FF) type, table 2 contain based on IP shock upstream and downstream values contain shocks parameter (velocity, density and magnetic field) create graphical analysis.
