On the night of April 9, a powerful class M1.5 flare occurred on the Sun. This was reported by the Laboratory of Solar Astronomy of the IKI and ISZF.
The activity began at 01:08 and ended at 01:36 Moscow time.
In addition, at 04:43, scientists recorded a new flare of level C3.8.
Depending on the power of X-ray radiation, solar flares are divided into five classes: A, B, C, M, and X. Class M flares cause minor radio interference on the daytime side of the Earth.
The minimum class A0.0 corresponds to a radiation power at the 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.
