Eight flares of the penultimate power class occurred on the Sun on January 17. This was reported by the Laboratory of Solar Astronomy of the IKI RAS and ISZF SB RAS.
In total, experts recorded 24 flares of class C and higher during the day.
The sun, it seems, has decided to stop scaring with a coronal hole for now and is starting to scare with spots again in the old fashioned way. In general, it's a good proven method. The area and number of active regions [sunspots] have started to grow again.
In addition, there are numerous signs that the solar corona is filling with energy. The main one is an increase in background radiation in the X-ray region of the spectrum. This indicates that the plasma temperature has reached several million degrees. Medium-class M flares began on Friday, January 17, there were eight of them.
Solar flares are classified according to the power of X-ray radiation into five categories: A, B, C, M and X. The minimum class A0.0 corresponds to a radiation power in Earth orbit of 10 nW per 1 sq. m. With each subsequent letter, the power increases by a factor of 10.
Solar flares are usually accompanied by plasma ejections, the clouds of which can reach Earth and cause magnetic storms.
At the end of December, two powerful flares hit the Earth. It was one of the most powerful bursts of solar activity in 2024. Scientists have made an alarming forecast: in the next two to three years, the number of magnetic storms will increase. Approximately until 2028, people will have to live in conditions of magnetic storms and auroras.
