A flare of the penultimate power class M was registered on the Sun on August 3. This was reported at the Institute of Applied Geophysics (FSBI "IPG").
On August 3 at 16:57 Moscow time, an M2.9 flare lasting 11 minutes was registered in the X-ray range in group of spots 4168 (N04E23).
Earlier, the Laboratory of Solar Astronomy of IKI RAS and ISZF SB RAS reported on the possibility of class M and X flares on weekends due to the formation of new active centers on the Sun.
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 at the Earth's orbit of 10 nanowatts per square meter. When moving to the next class, the power increases by 10 times. Flares can be accompanied by emissions of solar plasma, the clouds of which, reaching the Earth, can provoke magnetic storms.
Earlier, www1.ru reported that a fireworks display of 17 flares occurred on the Sun in less than two days: flare activity is growing strongly.
