Only part of the CME is directed towards Earth, so we expect the Earth will receive only a glancing blow, since the source region is pointing away from us on the right on the limb of the Sun as seen from Earth. Scientists classify solar flares according to their brightness in the x-ray wavelengths. There are three categories:. X-class flares are big; they are major events that can trigger radio blackouts around the whole world and long-lasting radiation storms in the upper atmosphere.
M-class flares are medium-sized; they generally cause brief radio blackouts that affect Earth's polar regions. The flare and solar ejection has also generated a storm of high-velocity particles, and the number of particles with ten million electron-volts of energy in the space near Earth is now 10, times greater than normal. The increase of particles at this energy level still poses no appreciable hazard to air travelers, astronauts or satellites, and the NOAA SEC rates this radiation storm as a moderate S2 to S3, on a scale that goes to S5.
Monday's solar flare produced an R4 radio blackout on the sunlit side of the Earth. The classification measures the disruption in radio communications. X-ray and ultraviolet light from the flare changed the structure of the Earth's electrically charged upper atmosphere ionosphere.
This affected radio communication frequencies that either pass through the ionosphere to satellites or are reflected by it to traverse the globe. Share Via. By hindustantimes.
