Photographer Captures Rare Aurora over Brazil During Intense Geomagnetic Storm (Photo)

On January 19 a powerful geomagnetic storm pushed auroral activity far beyond its normal high‑latitude bounds, producing a brief southern lights display over southern Brazil. Astrophotographer Egon Filter captured the faint purple‑red glow from Cambará do Sul, a location well outside the typical auroral zone. Scientists attribute the phenomenon to a diffuse equatorial aurora penetrating the South Atlantic Anomaly rather than a stable auroral red arc. The event underscores the growing intensity of solar activity and its capacity to affect lower latitudes.
