What is a solar radiation storm? | Help | SpaceWeatherLive
NOAA uses a five-level system called the S-scale, to indicate the severity of a solar radiation storm. This scale ranges from S1 to S5, with S1 being the lowest level and S5 being the highest level. Every S-level has a pfu (proton flux unit) threshold associated with it.
SPIS Toolbox
Solar radiation can be categorized into four classes: levels less than 2.6 kWh/m2 are classified as low solar radiation while solar irradiance between 2.6-3 kWh/m2 is moderate solar radiation; irradiance of between 3-4 kWh/m2 is high solar radiation and It is ...

The CMP10, manufactured by Kipp & Zonen, is an ISO Class A (secondary standard) pyranometer that monitors solar radiation for the full solar spectrum range. It connects directly to a Campbell Scientific data logger and is well-suited for meteorological networks and solar-energy research and development.
Solar Flares (Radio Blackouts)
The next level, ten times higher, is the "B" level (≥ 10 -7 W/m 2); followed by "C" flares (10 -6 W/m 2), "M" flares (10 -5 W/m 2), and finally "X" flares (10 -4 W/m 2). Radio blackouts are classified using a five-level NOAA Space …
What are the different types, or classes, of flares?
Scientists classify solar flares according to their X-ray brightness, in the wavelength range 1 to 8 Angstroms. Flares classes have names: A, B, C, M, and X, with A being the tiniest and X being the largest. Each category has nine subdivisions ranging from, e.g., C1 to C9, M1 …
