Scientists recorded eight powerful M-class flares on the Sun on July 28. This was reported by TASS With reference to data from the Institute of Applied Geophysics (FSBI “IPG”).
The first of the bursts (M7.9) occurred at 04:51 Moscow time, and the last (M1.7) at 17:22. These events were observed in various sunspot groups.
Scientists recorded the strongest flare near the X class at 04:57 Moscow time. According to IPG data, an M9.9 flare was detected in the X-ray spectrum in sunspot group 3766 (S07E10) and lasted 8 minutes.
Solar flares are divided into five categories based on their levels of X-ray radiation: A, B, C, M, and X. The minimum class, A0.0, corresponds to a radiation power of 10 nanowatts per square meter in Earth orbit. The power increases by a factor of 10 as you move to the next class.
This week, the US National Oceanic and Atmospheric Administration (NOAA) reportedHe said there was a 60% chance that dark plasma bursts, known as “cold” solar flares, could cause a radio blackout on Earth as early as this week.
Earlier scientists was recorded the first signals of a new solar activity cycle
