Looking at it too long will make hair grow on the palms of your hands.

Is it ever visible from Montana?

I think it's just the greenhouse gases going radioactive.

We drove a few miles to a dark spot, after the POES Northern Hemisphere map flared to a level-10.

We got a long, HUGE display around aproximately 11:30 to 12:30, MDT; south-western South Dakota. Started with a large 'rainbowish' milky arc feon NNW-NE, and rising to about 15-20 deg at its highest...then it broke into rays, pillars, and curtains. Lots of pulsing & flaring. THEN it suddenly flared from almost due west to beyond the spot on the horizon under Mars, and extended clear to zenith.

Mostly silvery-greenish, with some darker reds & purples.

I wouldn't be surprised if they were visible in Oklahoma & Arizona, since they were so hugely bright, and so high in our sky

Whole experience was enhanced by several meteors, and a long lsating, large, slow, spark-spitting fireball.

It is still flaring visibly even here in town.

Oh, roar a roar for Nora,
Nora Alice in the night.
For she has seen Aurora
Borealis burning bright.

A furore for our Nora!
And applaud Aurora seen!
Where, throughout the summer, has
Our Borealis been?

I saw the Northern Lights in upper Wisconsin about six years ago for the first time.

They lasted about 25 minutes and it was the coolest thing I've ever seen. The sky was completely black and they were really bright and very active.

This picture reminds of the ones I saw.
