Two near-top class power (M) flares were recorded on the Sun. This was reported by the Institute of Applied Geophysics.
On August 4, at 08:15 Moscow time, an M1.4 flare lasting 16 minutes was recorded in the X-ray range in sunspot group 4168 (N04E14).
An M2.1 flare occurred at 07:57 Moscow time in the same group of sunspots.
Solar flares are classified by 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 at Earth's orbit of 10 nW per square meter, and with the transition to the next class, the power increases by a factor of 10. Flares can be accompanied by emissions of solar plasma, the clouds of which, reaching Earth, can cause magnetic storms.
