Title: Study of the Ring Current Response to ICMEs and CIRs
Abstract:

We have conducted an investigation of the storm-time ring current to different solar wind drivers. To this end we have analysed measurements of protons and oxygen ions by the RBSPICE instrument on-board the NASA Van Allen Probes mission during a number of selected CME-driven and CIR-driven storms. To identify patterns of characteristic behaviour of the two ion species, we have studied the evolution of the ion pressure for all selected storms, using the method of superposed epoch analysis. This work is part of the Bachelor thesis of the leading author.
