MOSCOW, June 16 – RIA Novosti. Glow, fixed in the night sky over Chelyabinsk, most likely, is not the aurora borealis, and noctilucent clouds in the stratosphere, illuminated by the sun, told RIA Novosti Head of the Laboratory physics of the upper atmosphere of the Institute of Atmospheric Physics, Russian Academy of Sciences (IFARAN) Anatoly Semenov.
Sunday in the media have videos and eyewitness that night over Chelyabinsk observed glow like the aurora borealis.
“What I have seen – it is typical noctilucent clouds, not the aurora. Their perfectly visible at mid-latitudes, including here in the suburbs. They are located at an altitude of 81 km They are made up of microscopic ice crystals are formed and summer, “- said Semyonov.

He added that such clouds can be seen on the north side of the sky, because there is now the polar day, and the sun illuminates them over the horizon.
“We in the mid-latitudes plunge angle of the sun (below the horizon) is 12 degrees, we’re in the shade, so we can see them very well,” – he added.
When dissolved sky
Northern Lights – one of the most amazing natural phenomena. Despite its name, can be seen in the Southern Hemisphere, because it more accurately called “polar” and the romance and did say – Aurora Borealis. Scientists have described a “habitat” aurora – the so-called auroral ovals – the vast polar regions located asymmetrically around the geomagnetic poles. That is theoretically see the glow of the upper atmosphere can be both in Canada and Alaska, and Scandinavia, and in many other parts of the world.
worshiped since ancient times, and sometimes it catches up to the horror and warned of impending disaster, and at times promised happiness and longevity. Scientists have divided it into atoms and molecules, and artists – on the shades and halftones. Man has learned to predict its occurrence and even created a synthetic model. And put an invaluable service to the phenomenon itself. Read more about how people “use” Northern Lights
