Description
The work described here was performed during a two-months internship carried out in the framework of the ERASMUS project under an agreement between the Ioannina University and the INAF-Turin Astrophysical Observatory, in the period between mid-October and mid-December 2024.
Abstract
In this study, we analyzed two major geomagnetic storms that occurred in 2024. For our analysis, we used in-situ data from NASA’s Advanced Composition Explorer (ACE) spacecraft, specifically measurements from the SWEPAM instrument. We examined key plasma parameters such as proton density, magnetic field components, and bulk speed, while also calculating derived quantities like Alfvén speed, the convection electric field, and the Alfvénic Mach number. Our analysis covered the time intervals from 09/05/2024 to 13/05/2024 for the May geomagnetic storm and from 09/10/2024 to 10/10/2024 for the October storm, focusing on their evolution in relation to the Dst index. This study was conducted as part of a two-month Erasmus internship.
