A flare of the penultimate power class M was recorded 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 recorded in the X-ray range in spot group 4168 (N04E23).
Earlier, the Solar Astronomy Laboratory of the 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 into five classes depending on the power of X-ray radiation: A, B, C, M and X. The minimum class A0.0 corresponds to a radiation power in Earth orbit of 10 nanowatts per square meter. When moving 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 the Earth, can provoke magnetic storms.
Earlier www1.ru reported that a firework of 17 flares occurred on the Sun in less than two days: flare activity is growing strongly.
