Unprecedented Solar Storm Ignites Dazzling Northern Lights Across the U.S.

A strong geomagnetic storm, reaching G3 levels, sparked colorful aurora borealis as far south as Arizona in the United States, following four bursts of plasma from the sun. The delayed storm caused some uncertainty among aurora watchers, but patient sky watchers were rewarded with vibrant displays of red and green pillars in the sky. Despite the nearly full moon, the colors shined brightly. The solar storm may persist into Friday night in the United States, and more dazzling displays are expected in other regions. The sun's active spell is expected to continue, with additional bursts of geomagnetic activity likely in the coming months.
