Solar Flares: NOAA Space Weather Scale Classifies Radio Blackouts
Five-Level Scale Measures Flare Intensity
Radio blackouts are classified using a five-level NOAA Space Weather Scale directly related to the flares max peak. The scale ranges from R1 Minor to R5 Extreme, with each level indicating the severity of the radio blackout and the corresponding impact on communications.
