Summary: The sunspot cluster AR 3723, previously AR 3664 and AR 3697, returned with an M9.3 solar flare on June 23, 2024, near X-class intensity. It caused the most intense geomagnetic storm in 20 years. AR 3723 produced 28 M-class flares and 6 X-class flares during its last rotation. Solar physicist Keith Strong noted its significance. Solar flares can impact Earth's communications and technologies. Monitoring continues for potential geomagnetic storms and auroras.

I'm replacing the original 8-factor scoring system with a new and improved one. It doesn't use the original factors and gives much better significance scores.
