oK, here's a theory based on a bit of reasonable evidence that seems relevant considering your current speculation danman23. I've posted this exact idea in the other spiral threads, I'm a bit of a one trick pony in this race, but I think it's worth having a look at again.

Firstly I suggest that the EISCAT team are possibly performing a military experiment under the guise of this tequila sunrise thing and it involves a rocket/missile launch and the EISCAT facilities. Have a look at this:




This is a diagram of a method for making missiles undetectable by radar being explored by NASA and the US Navy. It involves a projectile that disperses a dust cloud and then the cloud is electrically charged using a few different methods including the use of a facility like EISCAT. The idea makes allot of sense in a few ways.

Firstly I should clarify that I believe the blue spiral looks like a rocket exhaust and I'm not working under the illusion that EISCAT can produce that intensity of optical energy. But, the really big, lighter spiral is quite faint and I am open minded about it's luminosity being some effect of the electrical charging of the dust cloud.

Also, the Navy experiment doesn't mention a spiral but I can see a couple of ways that could be factored into the idea. A/ the dust cloud is dispersed in a spiral, or B/ the electrical charging creates the spiral in some manner. It has been documented that artificial aurora's make a spiral and it is one of these effects that is unexplainable.

Oh yeah, it really does look like the trajectory of the missile coincides well with the Russian testing area, so this leaves open to speculation the idea that it is a Russian, EU, US joint effort. Why not?

Maybe.

(Thanks zorgon for the picture and the idea.)
