Three strong M-type flares occur on the Sun at night. This is reported in the data given above website Solar Astronomy Laboratory IKI RAS and ISTP SB RAS.
According to documents on the laboratory's website, on the night of December 29, three M-type flares appeared on the Sun, lasting from 00:03 Moscow time to 00:23 Moscow time with a maximum level at 00:13 Moscow time, from 01:01 Moscow time to 01:54 Moscow time with a maximum level at 01:39 Moscow time, reaching point M4.2, slightly smaller than the flare that occurred. occurred during the night of December 28, as well as from 02:57 Moscow time to 03:07 Moscow time and up to 03:02 Moscow time.
In addition, three more C-type flares occurred on the Sun.
Solar flares, depending on the strength of X-ray radiation, are divided into five classes: A, B, C, M and X. The minimum class A0.0 corresponds to a radiant power in Earth orbit of 10 nanowatts per square meter. When moving to the next letter, the power increases tenfold. Flares are often accompanied by solar plasma emissions, clouds of which, when reaching Earth, can cause magnetic storms.
