Scientists have recorded the most powerful radiation storm of the 21st century in the vicinity of Earth.

      A radiation storm of level S4 has begun in the vicinity of Earth for the first time in 24 years. This was reported by scientists from the Solar Astronomy Laboratory of the IKI RAS. "For the first time in the last two solar cycles, a radiation storm of level S4 is occurring in the vicinity of Earth! Level S5 exists only theoretically and has never been reached in modern observational history," the message states. As of 22:25 Moscow time, the flow of solar protons was 37,000 units. It is noted that the record values considered to be the highest in history were around 40,000 units, achieved in the last century. "This is higher than during the X17.2 flare in 2003. This is completely inexplicable! A record value has been reached in the 21st century!" scientists report.
