Northern Lights in Southern Skies: The Aurora Borealis and Sun Storms August 2010

The sun, on August 1, 2010 NASA/Corbis

On August 1st, almost the entire Earth-facing side of the sun erupted in a tumult of activity. There was a C3-class solar flare, a solar tsunami, multiple filaments of magnetism lifting off the stellar surface, large-scale shaking of the solar corona, radio bursts, a coronal mass ejection and more. This extreme ultraviolet snapshot from the Solar Dynamics Observatory shows the sun's northern hemisphere in mid-eruption.

There was considerable excitement in North America, with the news that on the night of August 3, 2010, an unusual set of sun storms might make the Aurora Borealis or Northern Lights, visible as far south as the 49th parallel, the latitude that forms much of the border between the US and Canada. There were multiple news articles in both Canadian and American papers online, suggesting people try taking a look into the night sky in the hopes that it would be clear enough, and this natural fireworks spectacular could be glimpsed by people who usually only see it in pictures. Many articles included explanations, the best I found being in Boston.com, here, and The Globe and Mail, here, as well as Wikipedia, here.

Just about the time I started wondering whether there were "Southern Lights" from the South Pole, I discovered, yes there are, the "Aurora Australis".

Indeed, aurorae can occur on other planets in the solar system too, as in the examples from Saturn and Jupiter below:

I enjoy these phenomena for the esthetics, and for the sense that nature, and the universe, bind us all together.

And what did I see? I didn't look...I only found out about it this morning! :(

Did you see the Aurora Borealis on August 3, 2010?
Have you seen it or the Aurora Australis on other occasions?

How amazingly beautiful! I already love to see the sky, I can't imagine what I'd do if I looked up and saw THIS! Wow! :)

Glad you finally found something to post about! ;-P

Chiara said...

Susanne--LOL :) Lots to post about. Many many drafts, some more drafty than others. Many many comments to make. Felled by the infamous MIGRAINES!!! Seriously looking to move to a place that doesn't have barometric bouncing!

I'm really glad you liked this post, though. I would love to see these for real too.

Thanks for your comment! :)

Susanne said...

Oh, I'm so sorry about your migraines. :(

I'd just noticed no new posts for about 5 days and had to tease you. Hope you are feeling much better soon!

Chiara said...

Susanne--I enjoyed the tease, and I am glad you noticed! Shall I tell you the tragic tale of the sudden train trip, and being left at the station while family went out for my nephew's birthday dinner without me? No, it is too tragic! :( :( :( LOL :) :P :D

Susanne said...

Awwww. :-(

Share only if you want.

Of course, I noticed! I look for new posts in my Google Reader daily. :)

Oooh wow! I love the look of the Aurora Australia!!! Although can't help feeling sad that I've never seen it :(

Wendy said...

I have seen them in past years when living in northern Alberta. Hopefully we will make a trip to the 'true north' one day to really see them. I'm sorry I missed this past event.

Also sorry about those awful headaches. Hope you finally outgrow them like I did.

Chiara said...

Susanne--thanks! I may save it for the culinary catastrophes Part II! :)

Ellen--glad you like the post! I hope you get to see the Aurora Australis for real some time! :)

Wendy--how wonderful that you have seen them even from "down South" :) I may have caught a glimpse when I was too young to remember. I should do a stint with the Arctic fly-in psychiatric team and try to see them for real and memorably.

Thanks to all 3 for your comments! :)
