On the night of April 14, a powerful class M1.6 flare was recorded on the Sun. This was reported by the Laboratory of Solar Astronomy of IKI and ISZF.
The flare began at 00:55, peaked at 01:02, and ended at 01:11. Disturbances were noticed in region 4055.
In total, nine more class M flares occurred on the Sun during April 13, indicating increased solar activity.
Solar flares, depending on the power of X-ray radiation, are divided into five main classes: 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 are capable of provoking magnetic storms on Earth.
