NOAA space weather scales

A means of communicating to the general public the current and future space weather conditions and their possible effects on people and systems. The scales were developed for three event types: geomagnetic storms (G-scale), solar radiation storms (S-scale), and radio blackouts (R-scale). They are attributed a number from 1 to 5 based on severity: 1 = minor, 2 = moderate, 3 = strong, 4 = severe, and 5 = extreme.
