A powerful class M flare was recorded on the Sun. This was reported by the press service of the Institute of Applied Geophysics (FSBI "IPG").
On January 29, at 07:08 Moscow time, an M1.0 flare lasting 48 minutes was recorded in the X-ray range in group of spots 3977 (N23E70).
According to the website of the Laboratory of Solar Astronomy of the IKI RAS and ISZF SB RAS, two more class C flares occurred on the same day.
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 m², with a transition to the next class, the power increases by a factor of 10.
Flares are accompanied by emissions of solar plasma. When clouds of solar plasma reach Earth, they can trigger magnetic storms.
Earlier, www1.ru reported that a flare of the penultimate power class occurred on the Sun on Monday morning.
