NASA’s observatories detected a strong X1.1 class solar flare on December 8, 2025, which represents one of the most extreme types of solar eruptions. This event, which follows another powerful flare in late November, underscores that the Sun is currently undergoing an intense period of high activity as it approaches the peak of its approximately 11-year solar cycle. While Earth’s atmosphere shields against the flare’s radiation, such events can disrupt technologies dependent on radio waves and potentially cause geomagnetic storms if followed by a coronal mass ejection (CME) aimed at Earth.
