Default Aurora Spirals in Norway & Finland 18th February

Just found a few images in a thread going at ATS.

Thought it would be interesting to mention them for you guys.

Some new spirals appear in the Aurora Borealis above Tromso Norway and somewhere in Finland.

Both pictures are taken the same day February 18th.

What I saw discussed is that many dismiss it as normal aurora... But thing is. The ones who know more about this say they have never seen or heard about spiral Auroras as seen above.
The are mostly in lines or curtain like formations etc.
And I must say I myself never heard about Aurora coming about into a spiral pattern visual.

Then there was some mention how the EISCAT with it's ionosphere heating can cause spiral like visuals in the aurora.

So question is was it on usage this day and the cause?

If it was ionosphere heating or not it would be interesting to go back to other meanings about the spirals...

Like the rock carvings found all over the world in the mountains? Could this be it? Just Aurora Borealis coming into spiral patterns? And looking at the carvings it's cause for alarm? The stuff is about to hit the fan already?
