Aurora Photos: Northern Lights Dazzle in Night-Sky Images

Solar Storm May Spark Dazzling Northern Lights Display

Skywatchers at high latitudes can expect spectacular aurora borealis displaysin the skies tonight (Aug. 5) thanks to a strong solar flare that hurled a cloud of plasma toward Earth on Aug. 2. The flare occurred when an intense magnetic event above sunspot 1261 hurled a stream of charged particles that's now headed toward Earth, according to SpaceWeather.com.

Also known as the Northern Lights, the aurora light show is the result of the interaction of these charged particles with Earth's magnetic field.

The image above, taken by instruments onboard NASA's Solar Dynamics Observatory, shows a powerful M9-class solar flare that erupted from the sun at 10:09 p.m. EDT on July 29 (0209 GMT July 30). M-Class flares are medium-strength events. The strongest type of solar eruption is class X, while class C represents the weakest, on the scale. The Aug. 2 flare registered as a middleclass M1 event.

Visitors to Denali National Park saw quite the light show this week as the northern lights glowed in the night.

Also called auroras, northern lights form when charged particles flow from the sun in a kind of "solar wind" and enter Earth's magnetic field, revving up electrically charged particles trapped there.

By the second week of August, the night sky above Denali is dark enough to see the northern lights. As Denali turns farther and farther away from the sun, the amount of darkness increases each night. Denali loses daylight rapidly in late August and September, so that by late September you don't have to burn the midnight oil to enjoy the night sky.

The light show in the above photo was seen over Denali's Toklat River. Denali spans 6 million acres of land in the Alaskan wilderness. The park is home to the tallest peak in North America, Mount McKinley, also known as Denali, which has a height of 20,237 feet (6,168 meters). "Denali," or "High One," was given its name by Athabascan native people. The mountain is part of the Alaskan Range, which covers some 600 miles (966 kilometers).
