Scientists at 15:06 Moscow time recorded a powerful solar flare in the X-ray range, which occurred in the group of sunspots 3889 (S07E26). This flare, belonging to class M9.5, lasted 31 minutes.
According to the Institute of Applied Geophysics (FSBI "IPG"), the event is close to class X, which is the most powerful in the classification of solar flares.
Solar flares are classified by the power of X-ray radiation into five classes: A, B, C, M, and X. Class A0.0 corresponds to the minimum radiation level in Earth's orbit, equal to 10 nanowatts per square meter. With an increase in the letter in the class, the radiation power increases tenfold. Such flares can be accompanied by emissions of solar plasma, which, moving towards the Earth, can cause magnetic storms that affect atmospheric phenomena and satellite systems.
Recently, solar activity has increased significantly, and over the past two days, the energy emitted by the Sun is cumulatively equal to the energy of five class X flares, which indicates a high degree of activity of our star.
