The solar flare from last week resulted in spectacular northern lights in parts of Minnesota and other northern states. NBC's Brian Williams reports.
The solar storm that swept past Earth over the weekend didn't disrupt any power grids, but it did turn on the auroral lights for skywatchers over a wide swath of North America, extending at least as far down as Arkansas.
SpaceWeather.com cataloged stunning photos from the usual places in northern climes, including Canadian provinces as well as the northern tier of the United States. But this particular solar storm — sparked by last Thursday's big coronal mass ejection, or CME — didn't stop there. Photographers sent in pictures from Arkansas as well as Ohio, Nebraska, Utah, California and other locales well south of the usual places. There were auroral images as well from Scotland, Hungary, and yes, from New Zealand, Tasmania and the South Pole at the other end of the world.
Observers knew they were in for something big, due to the fact that the flare associated with the solar eruption reached an extreme level of X1.4 on the classification scale for solar outbursts. The radio blast from a sunspot region known as AR 1520 resulted in a strong radio blackout for some high-frequency communication systems, according to the National Oceanic and Atmospheric Administration's Space Weather Prediction Center.
Extreme solar storms have been known to knock out electrical grids as well as satellites, but this one apparently had no ill effects. Today, the prediction center said the stormy space weather "is finally showing signs of weakening."
"No further significant activity has occurred, and while Region 1520 has become less of a threat, it still has the potential for further activity," the center reported.
The sun is heading toward the high point of its 11-year activity cycle, with the maximum expected next year. That means this weekend's storm could just be a foretaste of what's ahead for aurora-watchers and space weather forecasters over the coming months. In the meantime, check out this gallery featuring the latest pictures from the world's greatest light show:

Photographer Brad Goldpaint snapped multiple frames of the northern lights on July 15. "I had an incredible experience last night capturing the aurora borealis over Sparks Lake in Central Oregon," he said in an email sent on Sunday. For more of his work, check out the Goldpaint Photography website.
Photographer Brian Emfinger captured this time-lapse video view of the auroral display over Ozark, Ark., on July 15. "There was a very faint red glow off and on most of the night, but around 2 a.m. CDT it began increasing. Around 3 a.m. and 3:30 a.m. there were pretty good outbursts," Emfinger told SpaceWeather.com. For more from Emfinger, check out RealClearWx.com.

The subtle glow of the aurora competes with the glare of a signal light at the Ojibway Bay Marina, as captured over the weekend by photographer Robert Snache of Rama First Nation in Ontario. For more of Snache's pictures, check out Spirithands Photography's Facebook page.

Randy Halverson / Dakotalapse
Rare pinks and blues glow in the skies over Kennebec, S.D., in a picture of the northern lights captured by Randy Halverson on July 15. "It was bright to the eye at the time this was taken," Halverson told SpaceWeather.com. "Clouds made it difficult to get good pictures, though." More of Halverson's imagery can be seen on the Dakotalapse website.

Thanks Alan,they are beautiful pictures.
Ditto Linda!
Chromium particles are responsible for the northern and southern lights.
Actually I've just discovered that Chromium isn't all it's cracked up to be. It's even better than I could ever imagine!
I may really tout the positives of Chromium, but it's much more than what I could ever possibly say!
Without Chromium, it's likely that are world would cease to exist in it's present form!
Eugene - you must be a very sad and lonely person if the only way you can get your kicks is to go on-line to post lies. You are pathetic, and you certainly don't have a Ph.D. in anything. The northern and southern lights have absolutely nothing to do with chromium, and chromium is insignificant to whether the Earth continues to exist. Actually, chromium (VI) is highly toxic.
The northern lights result from emissions of photons in the Earth's upper atmosphere from ionized nitrogen atoms regaining an electron, and oxygen and nitrogen atoms returning from an excited state to ground state. They are ionized or excited by the collision of solar wind and magnetospheric particles being funneled down and accelerated along the Earth's magnetic field lines.
You 'scales67' are the idiot!! Chromium is not highly toxic.
Chromium is an essential nutrient required for normal sugar and fat metabolism
and works primarily by potentiating the action of insulin. It is present in the
entire body but with the highest concentrations in the liver, kidneys, spleen
and bone.
There is even a Recommended Daily Allowance (RDA), of 120 micrograms per day of Chromium.
It is sad to see people like you wasting space in these forums.
Um, "Dr" Euguene unless your stating that sugars, fats, my liver, kidneys, or spleen are causing the Northern and Southern lights....then I have to side with scales67 and say your first statement is a fallacy. Perhaps if you stated how Chromium causes the Northern and Southern lights instead of why it's important for our body then we all might not /facepalm when we read your comments.
Dr. Empty,
You must have bought your PhD through Fifty-Dollar-U prior to the 20th century, since you quite obviously are oblivious to what scales just tried to educate you about. C-VI is HIGHLY toxic & has been known to be since mining in the American West started heavily in the 19th century. Further, 6 forms of Chromium are known & listed carcinogens.
C-III, the only other type Chromium commonly found, is the one you speak of, but evidently aren't too knowledgable about. Yes, it is needed by the body as a trace element. 99% of people get ALL they need if they eat normal amounts of vegetables, meats, & bread. An over-intake of C-III is also toxic, just as C-VI. The symptoms are much less severe however, usually only skin rashes.
C-V is even more toxic, although rarely found in nature. However, the human body provides a perfect laboratory for the strong oxidizer C-VI to leave deposits of C-V on anything it can touch, which will sometimes lodge in the kidneys, intestines, & lungs. I know that will be confusing to you, but basically it means you've got problems then.
Just one other bit of knowledge for you that you are lacking. There is also an RDA, RDI, and/or DRV for Sodium, Vitamin K, Selenium, Zinc, Fluoride, & Potassium. ALL are toxic in elevated doses. The human body also seems to need trace amounts of Arsenic. Tank up good on that & tell me what happens. And finally, one of the most abundant & necessary chemicals on Earth can kill in a variety of ways ... H2O.
NOW you have a bit of info which can help you EARN a TRUE PhD. Hope that company who sold you that piece of paper on your wall has a money-back guarentee. I doubt it though, probably don't even exist any longer.
Don't bother replying, unless you just like having conversations with yourself ... which actually wouldn't surprise me. I don't enter extended debates with trolls. Adios.
It always amazes me when I see photos and time-lapse videos/photos of the solar flares. They are just stunning! Unlike many other incredible "weather" photos, however, there is not usually the same damage as, say, a tornado--which I also find impressive to watch.
Cody, thanks for posting your link. Your photos are breathtaking!
We got screwed over for seeing them around the Kalamazoo / BC, Michigan area. =(
Saw them 20 minutes north of Grand Rapids!
watch this LazyCash43.com
Totally awesome and coming to an outdoor theatre near you.
I live in Nevada and stayed up all night Saturday into Sunday morning and didn't see anything. I already read that the solar flare wasn't as strong as originally thought and the effects only covered the northern part of Canada. Why is everyone on here posting made up pics of an event that didn't happen? Yes, there was a solar flare. But NO, the "auroral lights" were not visible in the United States. It's beyond ridiculous that somebody has an agenda to make people think it did, that makes absolutely no sense.
So, because you couldn't see them in Nevada. There is no way anyone else in the US, could see them, or take photos of them, that makes perfect sense.
Stay curious ....
That reminds me ....
The car size rover "CURIOSITY" will be landing on Mars in a rather unique method ....
Thanks Alan ....
Behold the beauty of the skies and the stars says Proverbs.
you ain't seen nothing yet [60's song], read the book of revalation, whats comming is mind bending.
I dot have a book enlighten me ........
hey george, storms, this heat, wars, conflicts, maybe its revalation time. everything is going on word for word out of the book of revalation in the bible.
RANGER RICK, some people find peace, joy, and understanding in their Bibles. Not everyone interprets current events as consistent with events in The Revelation. Storms, heat waves, epidemics, pandemics, wars, floods, and famine are ALWAYS going on somewhere. We are not living in unusual times except for our population and our technology. In other words, there are more of us than ever, and for the first time in human history we are able to know the news from nearly every remote corner of the world almost instantaneously, so we find out about the famines & floods that have always been happening in all the other places, where we DON'T live, and occasionally where we do. Let me know if you see a beast with a hundred heads or a hundred hands or whatever it is. Otherwise, I'll be over here relaxing and enjoying the wonders of the universe, like auroras.
We had complete cloud cover where we live so we didn't see anything which makes these pictures all the neater to me. Thanks for all who posted them!!
