A powerful class M flare was recorded on the Sun on the night of April 12. This was reported by the Laboratory of Solar Astronomy of IKI and ISZF.
The activity began at 03:36 and ended at 03:55 Moscow time.
Solar flares are divided into five classes depending on the power of X-ray radiation: A, B, C, M and X. Class M flares can provoke minor radio interference on the daytime side of the Earth.
The minimum class A0.0 corresponds to a radiation power on Earth's orbit of 10 nW per 1 m². When moving to the next letter, the power increases by 10 times. Flares are accompanied by emissions of solar plasma, the clouds of which, reaching the Earth, are capable of provoking magnetic storms.
