Scientists registered eight powerful M-class solar flares on July 28.
As reported by Day.Az with reference to TASS, this was reported by the Institute of Applied Geophysics (Federal State Budgetary Institution “IPG”).
The first flare (M7.9) occurred at 05:51 Baku time, and the last (M1.7) at 18:22. The flares were registered in different groups of sunspots.
Scientists recorded the most powerful flare, close to class X, at 04:57 Moscow time. <...> “An 8-minute-long flare of M9.9 was recorded in the X-ray range in the sunspot group 3766 (S07E10),” the IPG reports.
In addition, after a series of flares, the level of influence of solar X-ray bursts on the Earth’s ionosphere rose to R2 (moderate) on a scale of five indicators, where the highest level is R5 (extreme). According to space weather monitoring, four flares (M1.6, M9.9, M7.9, M7.8) were accompanied by disruption of HF radio communications.
Solar flares are divided into five classes depending on the power of X-ray radiation: A, B, C, M and X. The minimum class A0.0 corresponds to a radiation power of 10 nanowatts per square meter in Earth orbit. When moving to the next letter, the power increases by 10 times. Flares are usually accompanied by emissions of solar plasma, clouds of which, reaching the Earth, can provoke magnetic storms.
