On September 23, a flare of the penultimate power class was recorded on the Sun, as reported by representatives of the Institute of Applied Geophysics (FSBI "IPG").
On September 23 at 13:34 Moscow time, an M1.0 flare (S03W24) lasting 26 minutes was recorded in the X-ray range.
The Laboratory of Solar Astronomy of IKI RAS and ISZF SB RAS noted that on September 23, a slightly increased flare activity is expected with moderate risks for the Earth.
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 square meter, and with each subsequent class, the power increases by 10 times. Flares can be accompanied by emissions of solar plasma, the clouds of which, reaching the Earth, can cause magnetic storms.
It should be noted that such phenomena can affect the operation of satellites and communication systems, so it is important to monitor solar activity.
