As the Report reports, this was reported to TASS at the Institute of Applied Geophysics (FSBI "IPG").
"On August 7, at 05:32 Moscow time, an M2.2 flare lasting 25 minutes was recorded in the X-ray range in the group of spots 4168 (N04W29)," the institute reports.
In total, seven outbreaks of this magnitude were recorded in August, with almost all outbreaks occurring in one group of spots.
Solar flares, depending on the X-ray power, are divided into five classes: A, B, C, M and X. The minimum class A0.0 corresponds to the radiation power in Earth orbit of 10 nanowatts per square meter. When moving to the next letter, the power increases 10 times. Flares can be accompanied by solar plasma emissions, the clouds of which, reaching the Earth, can provoke magnetic storms.
