Sun Unleashes Record-Breaking Solar Flare: Earth Hit in 25 Hours, Threatening GPS

• An X1.9-class solar flare from sunspot AR4341 erupted on January 18, 2026, releasing a coronal mass ejection (CME).
• The CME, traveling at 6 million km/hour, reached Earth in a record 25 hours instead of the usual 3-4 days, stunning scientists.
• The impact caused a severe G4-category geomagnetic storm, the second-highest level, leading to widespread aurora displays.
• The X1.9 flare caused an R3-level radio blackout, affecting communication systems and posing risks to GPS and aviation.
• Scientists warn of increased solar activity as the Sun nears its peak, emphasizing the need for advanced forecasting to protect technology.

Why It Matters: A powerful solar flare hit Earth in record time, causing a severe geomagnetic storm and threatening critical technology.
