Solar Proton Events Affecting the Earth Environment

ResourceID
spase://NOAA/Catalog/GOES/SPEs

Description
NOAA Space Weather Prediction Center (SWPC) Solar Proton Events (SPEs), or solar radiation storms, involve high-energy protons (\(>10\text{ MeV}\)) accelerating from the Sun, causing significant disruption to satellite electronics, GPS, HF radio communication, and astronaut safety. These events occur when protons follow magnetic field lines to Earth, lasting hours to days and affecting polar regions most.
