What Does SPE Stand For?
SPE stands for Solar Proton Event
SPE, or Solar Proton Event, refers to a significant burst of energetic protons emitted by the Sun, typically associated with solar flares and coronal mass ejections. These high-energy particles can pose risks to astronauts in space, disrupt satellite operations, and affect communication systems on Earth. Monitoring SPEs is crucial for space weather forecasting and ensuring the safety of technological infrastructure and human activities in space.
