ARLA/CLUSTER: Nova época de Auroras boreais no Circulo Polar Ártico

[João Costa > CT1FBF]

Aurora season begins, and a storm is coming

They're back. Auroras have returned to the Arctic Circle as the Midnight
Sun finally begins to fade.

Sightings on Aug. 23rd and 24th confirm that green auroras are now mixing

a high-speed stream of solar wind is expected to hit Earth's magnetic
field, possibly sparking G1-class geomagnetic storms.
