After a long lull, a class X flare occurred on the Sun, according to the Astro Alert scientific Telegram channel.
Disturbances were detected in the area of the receding sunspot group No. 4086. Because the flare occurred on the edge of the solar disk, it will have no impact on Earth; the event is more formal than practical.
Solar flares are classified by 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 Earth, can cause magnetic storms.
On Monday night, the Sun also erupted with a flare of the penultimate power class (M).
