A dazzling display of the northern lights (aurora borealis) with an intensity level exceeding Kp5 lit up the skies over Anchorage, Alaska, painting vibrant green and faint purple hues across the autumn landscape. The spectacle, visible across much of southern Alaska, was triggered by heightened solar wind activity following a geomagnetic storm caused by a coronal mass ejection (CME) from the Sun.
Locals, photographers, and tourists gathered in open areas and scenic viewpoints to witness the celestial phenomenon, which has been a symbol of Alaska’s natural beauty and Arctic identity for centuries. The northern lights occur when charged particles from the Sun collide with gases in Earth’s upper atmosphere, creating shimmering curtains of light that vary in color depending on altitude and the type of gas involved.
This event marks one of the strongest auroral displays of the 2025 season, offering both a visual treat and a reminder of the Sun’s powerful influence on Earth’s magnetic environment.
