In this master’s thesis, an analysis of the dynamics of five selected coronal mass ejections (CMEs), which are among the most powerful manifestations of solar activity, is presented. The analysis is based on publicly available images obtained with the LASCO C3 coronagraph aboard the SOHO satellite. Using freely accessible software, the position of the leading edge of each eruption in sequential images was determined, and the projected distances, velocities, and accelerations for the five selected events were calculated. Additionally, based on one representative processed and calibrated image per event, the mass of the ejected plasma was estimated through Thomson scattering. The obtained results clearly illustrate the dynamics of the eruptions and confirm the effectiveness of the presented methods for the basic analysis of such phenomena. Due to the accessibility of the software and the clear physical foundations, the method is well-suited for integration into physics or astronomy education, particularly in the form of research projects with gifted students.
