And the sky definitely was active again - actually, I've never before seen it this intense.

Instead of smoothly shifting shapes now it was big clouds, curves and waves appearing and disappearing rapidly. And they don't come and go randomly, but with a rhythm. So I quickly fetched my shaman drum and threw myself on the snow, watching the sky and beating the drum to the celestial rhythm. It was as if the whole sky was turned into a giant strobo light show, pulsating at about 160 bpm or so.

I didn't even try to capture any of it with a camera. But here is a link to Finnish national broadcasting company hosting a gallery of user-posted images: http://yle.fi/uutiset/lukijoiden_kuvat_revontulista_haikaisevat__laheta_...
