Earth-Directed Sunspot 4366 Prompts Possible Auroras
TL;DR Summary
Sunspot region 4366 has unleashed dozens of solar flares in 24 hours, including multiple M-class and X-class eruptions—the strongest since 2024—making it the most active sunspot in years. NOAA's SWPC says a coronal mass ejection is headed toward Earth but is likely to miss or only graze it, potentially sparking auroras at unusually low latitudes later this week.
