The Physics Department at the College of Science, University of Basrah, organized a scientific discussion panel entitled “Solar Storm Physics: Flares, Coronal Mass Ejections, and Associated Radio Waves,” presented by Dr. Firas Mahi, a lecturer in the Department of Physics, as part of scientific activities aimed at deepening understanding of physical phenomena with cosmic and space effects.
The seminar aimed to discuss the importance of solar events, one of the most prominent physical phenomena affecting near-Earth space, given their impact on communications, satellites, and sensitive technical systems.
The lecture included a comprehensive scientific analysis of solar explosions, particularly solar flares and coronal mass ejections (CMEs), focusing on the dynamic relationship between solar flares, CMEs, and the radiation accompanying them across the electromagnetic spectrum. The mechanism of solar flares was also explained as a sudden release of magnetic energy stored in the solar atmosphere, accompanied by high-energy X-ray and ultraviolet emissions.
The episode also addressed the phenomenon of coronal mass ejections as a massive release of plasma and magnetic field into interplanetary space, in addition to discussing the radio emissions associated with these events, particularly Type II emissions resulting from shock waves, and Type III emissions emitted by accelerated electrons, explaining their connection to charged particle flows and their effects in the interplanetary medium.
