On Monday, the number of solar flares of the penultimate power class M increased to nine, the press service of the Institute of Applied Geophysics (IPG) reported.
Earlier, on February 3, seven strong flares were registered. They occurred between 02:00 and 11:00 Moscow time.
Later, two more flares were recorded. At 16:18 Moscow time, an M6.1 flare with a duration of 16 minutes occurred in the group of sunspots 3981 (N06E15). Also, at 12:13 Moscow time, an M1.4 flare with a duration of 8 minutes was registered in the same group of spots (N06E22).
Solar flares are classified according to the power of X-ray radiation into five classes: A, B, C, M, and X. The minimum class A0.0 corresponds to a radiation power in Earth orbit of 10 nanowatts per 1 sq. m, and with the transition to the next class, the power increases by 10 times. Flares are often accompanied by emissions of solar plasma, the clouds of which, reaching the Earth, can cause magnetic storms.
Earlier www1.ru reported that four powerful M-class flares were recorded on the Sun.
