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.ELETTRONICOenTechnical reportFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation
