Auroras are the result of disturbances in the magnetosphere caused by solar wind. Some O+ ions ("conics") also seem accelerated in different ways by plasma processes associated with the aurora. It says no appearance is recorded in the Transactions of the French Academy of Sciences between 1666 and 1716. What Does The Name “Frankenstein” Actually Mean? 1 Luminosità dorata e rosea che precede il sorgere del sole || a. polare , fenomeno luminoso che si verifica nell'atmosfera polare [34][35], In 2016 more than fifty citizen science observations described what was to them an unknown type of aurora which they named "STEVE," for "Strong Thermal Emission Velocity Enhancement." The aurora borealis seems to be composed of a mass of electric matter, resembling in every respect, that generated by the electric galvanic battery. Day-to-day positions of the auroral ovals are posted on the Internet.[9]. The Dieri people of South Australia say that an auroral display is kootchee, an evil spirit creating a large fire. In another interpretation, the currents are the direct result of electron acceleration into the atmosphere by wave/particle interactions. Io, which has active volcanism and an ionosphere, is a particularly strong source, and its currents also generate radio emissions, which have been studied since 1955. However, Jupiter's aurorae are more complex. Why Do “Left” And “Right” Mean Liberal And Conservative? The history of China has rich and, possibly the oldest, records of the aurora borealis. Two factors to consider are the tilt of both the solar and Earth's axis to the ecliptic plane. [44] Protons are also associated with auroras, both discrete and diffuse. For other uses, see, Images of auroras from around the world, including those with rarer red and blue lights, Videos of the aurora australis taken by the crew of. The electrons responsible for the brightest forms of the aurora are well accounted for by their acceleration in the dynamic electric fields of plasma turbulence encountered during precipitation from the magnetosphere into the auroral atmosphere. As already mentioned, it happens most readily when the interplanetary field is directed southward, in a similar direction to the geomagnetic field in the inner regions of both the north magnetic pole and south magnetic pole. These arise from electric currents along field lines ("field aligned currents"), generated by a dynamo mechanism due to the relative motion between the rotating planet and the moving moon.
