Sometimes, after your eyes adapt to the dark, a spectacular sky appears. Such was the case earlier this month when one of the largest auroral displays in recent years appeared over northern locations like the border between Norway and Russia. Pictured in the above time-lapse movie, auroras flow over snow covered landscapes, trees, clouds, mountains and lakes found near Kirkenes, Norway. Many times the auroras are green, as high energy particles strike the Earth's atmosphere, causing the air to glow as electrons recombine with their oxygen hosts. Other colors are occasionally noticeable as atmospheric nitrogen also becomes affected. In later sequences the Moon and rising stars are also visible. With the Sun expected to become ever more active over the next few years, there may be many opportunities to see similarly spectacular auroras personally, even from areas much closer to the equator.

by Ole Christian Salomonsen

After six months and 50,000 still images, photographer and video artist Ole Christian Salomonsen presents us with this masterpiece video of the stunning aurora borealis shimmering in the cold night skies over Tromsø, Norway.

“A goal for me has been to try to preserve the real-time speed of the northern lights, or come as close as possible, and present it way I experienced it, instead of the northern lights just flashing over the sky in the blink of an eye. It may work on other time-lapse videos with skies and sunsets etc, but with the northern lights in focus, it should be presented in its true speed to reflect her beauty, IMO.”

– Ole Christian Salomonsen

The results are, simply put, beautiful. Especially to those of us who have never had the chance to witness the phenomenon of aurorae in person…but I can’t imagine anyone who wouldn’t be moved by this wonderful work of art.

The soundtrack was provided by local musical talent Per Wollen. The track “Aurora in the Sky”, released today, can be downloaded from iTunes.

Amazing job on this, Ole! Thanks for sharing with all of us, and thanks for permission to repost it here on LITD. One of the best aurora videos I have seen from The Land of the Northern Lights! (And to think it’s his “first video project”!)

Visit Ole’s in-progress site for more photos and videos, or check out his Flickr photostream.

Onde???????????
Em Portugal? De certeza?

Por acaso o Kp hoje chegou a 7 (escala de 1 a 10) ao final da tarde, o que é extremamente elevado e pode ter levado auroras bem a sul na Europa.

Agora o Kp segue a 3, bem mais baixo.
No domingo à noite, o Kp estava a 4 e vi uma aurora espantosa em Reykjavík.

Infelizmente sigo com tempo encoberto e aguaceiros de neve...


Já somos dois:D

Claro que não estava a pensar em Portugal onde é um fenómeno raríssimo... Mas sim no Norte da Europa;)
