The Sun's background radiation has increased significantly, reaching levels comparable to strong flares during its usual quiet phase. This surge is unprecedented, with the flash activity index hitting a rare red level 8 out of 10 for the first time since June.

Scientists at the Laboratory of Solar Astronomy at the Institute of Solar-Terrestrial Physics RAS have detected 11 flares today, with 2 being particularly intense, one of which peaked at M4.8. This unexpected spike in solar activity has left experts intrigued and closely monitoring further developments.
