What is the typical source and timing associated with Solar Particle Events (SPEs)?
Answer
Bursts of high-energy protons and electrons ejected from the Sun, usually accompanying flares or CMEs.
SPEs are dramatic, intermittent threats consisting of high-energy protons and electrons released from the Sun, often associated with major solar activity like coronal mass ejections.
