5 years ago21 views

MINOR RADIATION STORM: Energetic solar protons are flying past Earth today. The particles were accelerated in our direction by the M6-class flare of April 11th (see below). They can be seen hitting and speckling the detector of the SOHO spacecraft in this movie of the explosion (labeled image). NOAA ranks the ongoing radiation storm as S1, which is considered a minor event.
