A rare aurora appeared briefly over southern Brazil on Jan. 19 during a powerful geomagnetic storm. Luckily for us, one photographer was at the right place at the right time to capture the fleeting scene.
Astrophotographer Egon Filter captured the faint purple-red glow from Cambará do Sul, in Brazil's Rio Grande do Sul state, during the peak of the geomagnetic storm. Auroras are typically confined to high latitudes near Earth's north and south magnetic poles, making sightings in the Southern Hemisphere this far north of Antarctica very rare.
