The Solar Activity Monitoring Center reported that two powerful class X flares occurred on the Sun on December 8. They were recorded on December 8 at 01:15 and 12:06.
Specialists noted that the duration of the second flare was 13 minutes.
Depending on the level of X-ray radiation, solar flares are divided into five categories: A, B, C, M, and X. The weakest level of radiation corresponds to class A0.0, which is 10 nanowatts per square meter in Earth orbit. With each subsequent letter, the radiation power increases tenfold.
Solar flares are often accompanied by emissions of solar plasma, which, reaching Earth, can cause magnetic storms.
Immediately eight powerful class M flares occurred on the Sun on November 18. Experts also recorded disruptions in shortwave radio communications. Prior to that, another powerful flare, close to class X, occurred on November 10. It lasted 31 minutes.
