Aurora Timelapse Over Italian Alps

Explanation: Did you see last night's aurora? This question was relevant around much of the world a few days ago because a powerful auroral storm became visible unusually far from the Earth's poles. The cause was a giant X-class solar flare on Tuesday that launched energetic electrons and protons into the Solar System, connecting to the Earth via our planet's magnetic field. A red glow of these particles striking oxygen atoms high in Earth's atmosphere pervades the frame, while vertical streaks dance. The featured video shows a one-hour timelapse as seen from Cortina d'Ampezzo over Alps Mountain peaks in northern Italy. Stars from our Milky Way Galaxy dot the background while streaks from airplanes and satellites punctuate the foreground. The high recent activity of our Sun is likely to continue to produce picturesque auroras over Earth during the next year or so.

How about a full ten hours, dusk to dawn, in two minutes? The aurora never completely stopped.

Nice video Chris. Thanks. The aurora really gets red about a minute into the video. The planes really shoot across the screen.

A joy to watch! Even the music is in tune with the auroral display, at 1:05 there's a dramatic minor tone shift just as the sky turns dramatically red! And it all ends so peacefully…
