A flare of the penultimate class M occurred on the Sun. This was reported at the E.K. Fedorov Institute of Applied Geophysics.
On May 14 at 06.25 Moscow time, an M5.3 flare with a duration of 37 minutes was recorded in the X-ray range in group of spots 4087 (N17E68).
This is the second flare on the Sun in the last 24 hours, which was recorded after a long lull. Scientists observed the most powerful X1.2 flare on May 13 at 19.20 (Moscow time).
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, can cause magnetic storms.
