On Tuesday, December 24, five class M flares occurred on the Sun. It is noted that the first and most powerful flare of the day occurred on Tuesday night.
Around 03:19, scientists recorded an M4.7 flare lasting ten minutes in the X-ray range in sunspot group 3932 (S18E23). In addition, there were two M1.1 flares, as well as two M1.0 and M4.2 flares.
Depending on the power of X-ray radiation, solar flares are divided into five main classes: A, B, C, M, and X.
The minimum class A0.0 corresponds to a radiation power at Earth's orbit of 10 nW per 1 sq. m. When moving to the next letter, the power increases by a factor of 10.
As a rule, flares are accompanied by emissions of solar plasma, the clouds of which, reaching the Earth, can provoke magnetic storms.
