Light Pillars in Minnesota

We had 'light pillars' last night all around the Twin Cities.
VERY-VERY-COOL!!

If you've never seen them, they are like a ground based localized version of
the Northern Lights - only they're all around you.

It looks like 1,000 search lights all pointing straight up to the heavens.
The pictures on the TV website DO NOT do the view justice. And colors too.
Simply beautiful.

Why, on nights like these, the ground source light doesn't diffuse more as
it goes up is beyond me - as you can see in the links, pillars of light are
formed ...somehow??

In my lifetime I've seen light pillars fill the night sky - twice now.

It's the Bat-Light, Boywonder!

Too cool! Thanks,
Jim

God, it's scary to know that someone else is as warped as me. That was *my*
first thought, too!

So what, exactly, causes this phenomenon?

A city council (or business) with some money to spend, renting spotlights?

I've seen the local skating rink light pillars as a kid - I remember those.
But to have the whole night sky filled with what look the Northern Lights,
along with rows upon rows of colorful light pillars, in any direction you
look - that's pretty rare ...for me anyway.

Cool! I had never heard of this type of phenomena before. I'm guessing
that it takes pretty cold, and relatively rare conditions.

In Ohio, (where I grew up) when it was snowing, the ceilings were usually
low, and the temps were usually not far below freezing. Not the right
conditions, I suppose.

OK, I'll bite. What is the connection of the light pillars to Tron?

From http://wcco.com/weathernews/local_story_337230308.html:
Light pillars are formed when ice crystals in the sky refract the light from
ground light sources. When enough of the crystals align, pillars of light
appear in the sky.

Plate ice crystals, which are also responsible for sundogs.

Here's a wicked 'sundog' with ALL the possible reflection
and refraction patterns possible. A real photo taken at
the southpole.
