Looks like there is a chance that tomorrow night will be a good chance for viewing the aurora borealis for some people:

Aww, I was hoping this was more of a heads-up like “Testing '20’s-style Tesla death-ray beam17b at 23:04 CDT-- watch for aurora borealis, ignition of atmosphere also possible.”

Seriously, though. As the son of a dedicated solar astrophysicist, I agree that this could be pretty cool.

Folks, if you don’t want to be a nighttime astronomer when you grow up, just look at the sun.

I’m kind of expecting all the cell phones to stop working, myself.

Relax. When the cell phones and communications networks go down, the aliens will attack, using the Aurora as cover on their approach. So it’ll still be cool.

Or a radio astronomer, or an X-ray astronomer, or heck, just a professional astronomer. 😉

I’m hearing that it may be visible as far south as 38.

“It’s just the northern lights, mother!”

Sadly, that is the second thing I thought of when I heard this on the news today\*. The first was, “wow, cool!” They are predicting mostly cloudy weather here but I will probably go out for a look anyway.

What time is supposed to be best for viewing? I heard one report say after midnight was best but I heard another say the moon would be rising around midnight so earlier would be better.

\*It’s a Simpsons reference.

Currently the estimated planetary K-index is only 6, which is not quite high enough for the aurora to be seen here in Chicago. It MIGHT be visible on the north horizon in dark sky areas.

I have at least a slim chance, from what I hear. It’s certainl clear enough, and I’m pretty far north. I’ll have to give it a shot. It would be really cool if I could, I’ve never seen them.

Similar predictions are being made for the aurora australis in [Tasmania](http://www.themercury.com.au/article/2010/08/04/163461_todays-news.html) and [southern New Zealand](http://www.stuff.co.nz/southland-times/news/3986018/Solar-blast-could-light-night-sky).

This is from a Boston paper so I assume those are east coast times.

I think I could die happy if I ever saw the fabled Northern Lights. I’ve wanted to see them since I was a kid reading Jack London. Hell, I lived for a long time in South Dakota and never saw them. I guess I’m fated to never see them.
