Solar Particle Events

Solar Particle Events (SPEs) are bursts of energetic particles, mainly protons and electrons, emitted by the Sun during solar flares and coronal mass ejections. These high-energy particles travel through space at nearly the speed of light and can reach Earth within minutes to hours. SPEs can pose radiation risks to astronauts, satellites, and high-altitude flights by damaging electronics and increasing radiation exposure. Monitoring solar activity helps predict these events, allowing for precautions to protect people and technology in space and air travel systems.
