On December 24, five M-class flares occurred on the Sun. The Institute of Applied Geophysics informed TASS that the first and most powerful eruption of the day took place on Tuesday night.
"On December 24, at 03:19 Moscow time, a 10-minute long M4.7 X-ray flare was detected in sunspot group 3932 (S18E23)," the report said.
In addition, there were M1.0 and M4.2 outbreaks, as well as two M1.1 outbreaks.
Solar flares, depending on the power of X-ray radiation, are divided into five classes: A, B, C, M and X. The minimum class A0.0 corresponds to a radiation power of 10 nW in 1 square meter of the Earth's orbit. m: When moving to the next letter, the power increases 10 times. Flares are usually accompanied by solar plasma emissions, clouds of which, reaching Earth, can trigger magnetic storms.
