Another powerful flare has occurred on the Sun, which is expected to cause minor magnetic storms on Earth on October 28. They will last from 06:00 to 15:00.
A powerful flare on the Sun, with a strength of X1.8, occurred at approximately 10 a.m. on October 26.
According to forecasts, this will cause weak magnetic storms, class G1.
Professor Sergey Yazev of Irkutsk State University told TASS that photographs taken by the SDO orbital observatory showed a huge group of magnetic loops that formed after the flare. But the ejection "flew away" to the side, so strong magnetic storms are not expected on Earth.
Depending on the intensity of X-ray radiation, solar flares are classified into five levels: A, B, C, M, and X.
The weakest level — A0.0 — corresponds to a radiation power of 10 nanowatts per square meter in Earth orbit. With each subsequent letter, the power increases by a factor of 10.
Flares are often accompanied by emissions of solar plasma, which, when reaching Earth, can cause magnetic storms.
Previously, the strongest magnetic storm occurred on Earth in the second half of September. It caused auroras in the western hemisphere.
