A new natural phenomenon is observed in the territory continent. A bright red arc, invisible to the naked eye, has already been discovered in the sky over many countries of Europe when using modern cameras, science.nbcnews writes.

When high-energy flows, charged particles arrive at Earth after a solar flare, they cause the so-called geomagnetic storms. These events are disturbances in the magnetosphere, parts of the earth’s atmosphere where the magnetic field of the planet dominates. The most dramatic consequences of these giant storms are vivid auroras in the corresponding regions of the Earth. But the result of the storm expressed in other amazing consequences, for example, weakly a luminous red arc high in the ionosphere. It is electrically charged parts of the Earth’s atmosphere extending from 50 to 370 miles (from 85 to 600 km) above the Earth. Arcs emit very specific wavelengths of red light but they are too weak to be was to see with the naked eye. They appear in lower latitudes, in contrast to the auroras, which are usually observed in higher latitudes. At first, scientists thought it was too big light pollution in Europe makes it difficult to see the dim red arc. But now, the new Observatory (ASIAGO) located in the north Italy, uses cameras with highly sensitive sensors and fisheye lens to observe these red arcs and faintly auroras throughout most of the continent.

After comparing his observations with satellite and ground-based observations, researchers found that the red arcs reach Europe, stretching from Ireland to west to Belarus in the east. The fact that researchers are now able to see these arcs in Europe means that by combining similar data from America and the Pacific, scientists can now observe how far the arcs extend over vast distances over the planet. And “in this way, how long is the magnetosphere takes a process to “drain its storm energy,” says Researcher Michael Mendillo, space physicist from Boston University. (Red arcs occur when oxygen atoms in the ionosphere emits light after being excited by electrons, heated at high altitudes in the Earth’s magnetosphere.) Such data in in turn help scientists analyze the impact of space real-time radio communications and used in space weather modeling projects, added the researcher. Scientists have detailed their findings online February 25 in Space Weather Magazine.
