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 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 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 Earth, can provoke magnetic storms.
