After a long lull, the Sun erupted with a flare of the penultimate power class (M). The flare was recorded on Monday night at the Institute of Applied Geophysics (FSBI "IPG").
On May 2 at 03:01 Moscow time, an M1.9 flare lasting 11 minutes was recorded in the X-ray range in group of spots 4079 (N08W89).
Over the past day, the level of influence of solar X-ray bursts on the Earth's ionosphere reached R1, which corresponds to a weak impact. The degree of disturbance of the Earth's magnetic field was estimated as G1, which indicates weak magnetic storms.
Solar flares are classified according to the power of X-ray radiation into five classes — A, B, C, M and X. The minimum class A0.0 corresponds to a radiation power in Earth orbit of 10 nW per 1 sq. m, and with the transition to the next class, the power increases by 10 times. Flares can be accompanied by emissions of solar plasma, the clouds of which, reaching the Earth, are capable of causing magnetic storms.
Earlier www1.ru reported that powerful solar flares may start at any second: spots of incredible sizes were recorded in the CrAO.
