Frank Olsen reports that the weather in arctic part of Norway has been fantastic lately. Even so, the aurora are starting to make nightly appearances.

“I was standing on the very tip of an island in Vesterålen with a spectacular view, looking out on the Atlantic ocean,” he said. “With the full moon behind me, the clouds were amazing.”

Clouds mixed in with the aurora made for some lovely views. In all, Frank said he nabbed almost 400 images on his memory card! See another shot, below.

As we’ve said previously, these gorgeous sights must be payback for enduring the long winters in northern Norway. You can see more of Frank’s beautiful imagery of aurora, the night sky and more at his Flickr page, his website (he has prints for sale) or his Facebook page.

Aurora season must have started in Scandinavia! Frank Olsen just posted this fantastic shot of the Aurora Borealis dancing across the sky and reflecting on the water in Norway, and below, astrophotographer Göran Strand recently captured shots of the aurora from northern Sweden. Enjoy these shimmering beauties and we look forward to seeing more aurora as the summer winds down in the northern hemisphere.

Your Guide To When, Where and How To See The Aurora Borealis

As an amateur astronomer, two of the most frequently questions I’m asked are “When is the best time to see the aurora borealis and where is the best place?” In terms of place, two locations comes to mind: Churchill, Manitoba and Tromso, Norway. But until such time as the transporter is invented, most of us will be staying closer to home. The simple answer is north and the farther north the better.

As for the time, in the northern border states of the US, auroras occur fairly regularly around the time of solar maximum, when the sun peaks in storm activity. The current solar cycle tops out this summer and fall, so your chances at seeing northern lights are far better now than a year and a half ago when solar activity saw a steep decline during a protracted minimum.

Military Aurora Research Website Goes Dark As HAARP Facility Enters Contract Negotiations

A military program to investigate auroras in the north appears to have been suspended.

The High Frequency Active Auroral Research Program (HAARP)’s website (dead link here) is not available right now, and there’s been some media speculation about the program’s future. So far, though, our attempts to learn more about the situation have turned up little information.

“Currently the site is abandoned. It comes down to money. We don’t have any,” said James Keeney, who reportedly manages the HAARP project at Kirtland Air Force Base, in a report published by the American Radio Relay League earlier this week.

When Universe Today reached out to Keeney, however, he declined comment. We also got in touch with the public affairs officials at Kirtland Air Force Base, who said no one was immediately available for an interview and provided this statement:

“HAARP is currently in contract negotiations and our policy is not to comment on current contract negotiations,” stated Marie M. Vanover, the director of Kirtland public affairs. “HAARP’s website is expected to be reopened and populated with the new and current information within 2-3 weeks.”

The program is jointly managed by the U.S. Air Force Research Laboratory and the U.S. Naval Research Laboratory to investigate activity in the ionosphere, the region of the Earth’s atmosphere where auroras occur. It includes an array of dozens of antennas that, media reports say, energize parts of the ionosphere.

HAARP is also the target of many conspiracy theories, ranging from warnings that it would trigger a change in the Earth’s magnetic poles to accusations that it is actually a weapon prototype. You can read more about the unproven allegations in this 2009 Wired article.

We’ll keep you posted on the facility’s status as we hear more.

Auroras Dance Over Northern U.S. Last Night, May Return Tonight

A thick green arc of aurora settled in for the night last night. It was about 5 degrees thick and some 10 degrees high. A faint but colorful diffuse aurora glowed above it. All photos taken with a 16-35 mm lens at f/2.8 and 30-second time exposure. Credit: Bob King

A burst of energetic particles from the Sun called a coronal mass ejection peppered Earth’s magnetic field yesterday afternoon sparking a modest but beautiful all-night display of the aurora borealis. Another light show may be in the offing tonight for skywatchers living in the northern U.S.,  Canada and northern Europe.

Around 1 a.m. the arc became more active, sending up occasional rays that lasted from about a minute before fading away and being replaced by another. Credit: Bob King

Pale green fingers of light splayed across the northern sky at twilight’s end came as a surprise. NOAA space weather forecasters had predicted little activity. These soon faded but a thick, fuzzy arc persisted throughout the night. It arched from horizon to horizon across the northern sky like a pallid, monochromatic rainbow. Such arcs are common. Often the aurora never gets past this stage and simmers quietly or even fades away during the night.

Not this one. Around local midnight (1 a.m. CDT) here in Duluth, Minn. small bright spots and a series of tall, faint rays punctuated the arc and over the span of a half-hour completely reshaped it into loopy rayed arcs resembling a crown.

To the eye, the brightest parts of the aurora appeared green, but the taffy-stretched rays were colorless. The camera’s sensitivity coupled with a 30-second time exposure revealed striking pinks and hints of blue. Both pink and green colors are caused by the emission of light from oxygen atoms.

Bombarded by high-speed solar wind electrons and protons, they get jazzed into higher energy states. When the atoms return to rest, each spits out a photon of green or red light. All those tiny flashes add up. Multiplied by the billions of atoms that exist even in the rarefied air at the aurora’s typical 60-150 mile (100-250 km) altitude and you get heavenly eye candy.

I started watching the northern lights at 11 from home then took a drive to darker skies. Even at dawn’s 3 a.m. start, the green arc held its own shot through with rays that occasionally towered halfway up the northern sky. While this display wasn’t a grand spectacle like some auroras, it possessed a certain majesty the same way a long, slow movement concludes a great symphony.

Chances for more of the same continues through tonight and possibly into tomorrow, so keep a watch on the northern sky before you hit the hay tonight. If you see something green and glowing it you might be in for a treat.

In another installment, I’ll share tips on how best to see the northern lights and share several excellent tools you can use for predicting when they might occur.

Weekend Auroras Fill the Sky!

I was personally so pumped to have seen the Aurora Borealis over the weekend in Central Minnesota! It was a beautiful display of a green and white glow with high, towering, bright spires. Unfortunately, I was in the car at the time, and I definitely need to upgrade my camera to be able to take images of the aurora. But lucky for us, astrophotographers from both hemispheres captured gorgeous shots of the Aurora Borealis and Aurora Australis.

According to SpaceWeather.com, the Earth passed through a region of south-pointing magnetism in the solar wind on June 28, “and the encounter set off one of the finest geomagnetic storms of the current solar cycle.”

This shot from Colin Chatfield shows the awesome auroral scenes over Saskatchewan.

Yep, you really want to click on this image to see the larger version on Flickr. Wow — what a view!!

This is a 360° horizon pan, seen by Alan Dyer — who has an aptly named website, The Amazing Sky. This is a view seen from southern Alberta on June 5, 2013, and there is a lot going on in this image. Alan described it on Flickr: “There’s the Milky Way arching across the sky on the right, a low aurora to the north, perpetual twilight glow to the north (left of center) and bands of green airglow across the sky. Left of the house and also left of the main area of Milky Way are horizon glows from urban light pollution. A satellite, the ESA Einstein ATV going to the ISS, is at left of frame.”

I get extremely excited if I can see *one* of those things in a night, and here Alan has captured all at once — superb!

But wait, there’s more!

On June 10, Alan was able to take a timelapse of the Northern Lights and some noctilucent clouds, and it is gorgeous. See below:

Alan said on his website, “This was certainly one of the best NLC displays I’d seen and my best shot at capturing them.”

Find out more about this video here, and Alan shared his technical data on the image:
The Panorama was stitched in PTGui software from 8 images taken at 45° spacing with the 8mm lens at f/3.5 on the Canon 5D MkII at ISO 3200. Each is an untracked 1 minute exposure.

Weekend Aurora Surprise

An unexpected arrival of a surprisingly strong (6 KP) geomagnetic storm from the Sun provided an amazing weekend for astrophotographers. Stargazers from both hemispheres were treated with seeing the aurora. We already posted the images from Mike Hollingshead seeing the aurora and red sprite lightning in Iowa, but here are some more great views, including this gorgeous shot of the aurora over Crater Lake in Oregon, from astrophotographer Brad Goldpaint, with the added intrigue of the International Space Station flying over at 2:35 am, local time. He’s also provided an amazing video, too, below.

“I drove to Crater Lake National Park last night to photograph the Milky Way rising above the rim,” Goldpaint said via email to Universe Today. “I’ve waited months for the roads to open and spring storms to pass, so I could spend a solitude night with the stars. Near 11pm, I was staring upward towards a clear night sky when suddenly, without much warning, an unmistakable faint glow of the aurora borealis began erupting in front of me. I quickly packed up my gear, hiked down to my truck, and sped to a north facing location. With adrenaline pumping, I raced to the edge of the caldera, set up a time-lapse sequence, and watched northern lights dance until sunrise. The moon rose around 2am and blanketed the surrounding landscape with a faint glow, adding depth and texture to the shot.”

Incredible Astrophoto: Rare Red Sprite Lightning Shows Up During Aurora

Red sprite lightning appears in the sky with an aurora, as well as a distant thunderstorm, near Denison, Iowa on May 31, 2013. Credit and copyright: Mike Hollingshead, extremeinstability.com

“Holy crap, this is the rarest scene I’ve ever captured and likely ever will,” said photographer Mike Hollingshead. “I was standing there just watching when bam, big red sprites ‘squirting’ up into the air in the aurora.”

Mike said was hoping to see the aurora the night of May 31, 2013, and felt lucky when he saw a faint yellow glow begin to rise in the skies. At the same time, a thunderstorm could be seen off on the horizon and almost before he could even ponder the possibility of seeing something unusual, sprites started appearing.

This is an extremely rare event to be captured on film; in fact an image appearing just a few days ago on Astronomy Picture of the Day (APOD) on May 22 showed red sprite lighting with an aurora, and the APOD team said the image was a “candidate for the first color image ever recorded of a sprite and aurora together.”

“Sprites were first imaged in 1989 accidentally and first color photograph in 1994,” wrote Mike on his Extreme Instability website. “Recent. But with auroras, evidently it is possible the very first time was a couple freaking weeks before this one of mine. It’s that crazy rare.”

Sprites are huge electrical discharges that occur high above thunderstorm clouds. They are rare, but at least one has been captured on film from the International Space Station. They are triggered by the discharges of positive lightning between an underlying thundercloud and the ground. They often occur in clusters within the altitude range 50–90 km above the Earth’s surface.

You can read all the details on Mike’s website. And Mike also got his wish for seeing great auroras that night:
