Auroral Corona
Postagem: 01/01/2026
Cycle 25 solar maximum made 2025 a great year for aurora borealis (or aurora australis) on planet Earth. And the high level of solar activity should extend into 2026. So, while you're celebrating the arrival of the new year, check out this spectacular auroral display that erupted in starry night skies over Kirkjufell, Iceland. The awesome auroral corona, energetic curtains of light streaming from directly overhead, was witnessed during a strong geomagnetic storm triggered by intense solar activity near the March 2025 equinox. This boreal skyscape captures the evocative display in a 21 frame panoramic mosaic.
