12350 BC: The Most Powerful Solar Storm Ever Recorded

Scientists have discovered the most powerful solar particle storm ever recorded, dating back to 12350 BC during the last Ice Age. Using a newly developed model, SOCOL:14C-Ex, researchers determined the storm was 18% stronger than the previously strongest known event in 775 AD, and over 500 times more intense than the largest storm of the satellite era (2005). This finding significantly expands our understanding of solar activity's intensity and timeline, providing crucial data for assessing risks to modern infrastructure from future solar storms. The model's accuracy was validated using 14,300-year-old wood samples from the French Alps.
