On the night of October 29th, 2025, there was a brief display of the
relatively rare phenomenon known as The Dunes over Ørsta, Norway.

The foreground featured a bright green aurora band, the more delicate (and faint) auroral waves unfolded behind it. The faint undulating patterns stretched horizontally across the sky, resembling ripples in sand.

A phenomenon linked to atmospheric gravity waves that is modulating the aurora’s brightness at higher altitudes.

The Dunes lasted for about 10 – 15 minutes, before they gradually vanished.
