aurora solar wikipedia

According to Hearne, the Dene people saw the resemblance between an aurora and the sparks produced when caribou fur is stroked. At that time, finance was not yet all in place, but SolarReserve still anticipated commencing construction in mid-2018 and taking 650 workers two and a half years to build it. Fundamentally, Poisson's equation indicates that there can be no configuration of charge resulting in a net potential drop. This is why there is a color differential with altitude; at high altitudes oxygen red dominates, then oxygen green and nitrogen blue/purple/red, then finally nitrogen blue/purple/red when collisions prevent oxygen from emitting anything. The instantaneous distribution of auroras ("auroral oval")[4] is slightly different, being centered about 3–5° nightward of the magnetic pole, so that auroral arcs reach furthest toward the equator when the magnetic pole in question is in between the observer and the Sun. The resulting ionization and excitation of atmospheric constituents emit light of varying color and complexity. During magnetic storms, in … On the other hand, positive ions also reach the ionosphere at such time, with energies of 20–30 keV, suggesting they might be an "overflow" along magnetic field lines of the copious "ring current" ions accelerated at such times, by processes different from the ones described above. By a strange twist of physics, the magnetic disturbance on the ground due to the main current almost cancels out, so most of the observed effect of auroras is due to a secondary current, the auroral electrojet. 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. Ionospheric resistance has a complex nature, and leads to a secondary Hall current flow. The history of China has rich and, possibly the oldest, records of the aurora borealis. Different layers of the film emulsion respond differently to lower light levels, and choice of a film can be very important. The period between approximately 1645 to 1715 corresponds to the Maunder minimum in sunspot activity. [10][11] The southern counterpart, the aurora australis or the southern lights, has features almost identical to the aurora borealis and changes simultaneously with changes in the northern auroral zone. [85] It quotes Halley as saying that before the aurora of 1716, no such phenomenon had been recorded for more than 80 years, and none of any consequence since 1574.

The ultimate energy source of the aurora is the solar wind flowing past the Earth. The varying intensity of the solar wind produces effects of different magnitudes but includes one or more of the following physical scenarios. Green is the most common color. The aurora was located at Terra Cimmeria, in the region of 177° East, 52° South. It was expected to cost A$650M to build, including a A$110M loan from the Federal Government. Venus has no magnetic field and so Venusian auroras appear as bright and diffuse patches of varying shape and intensity, sometimes distributed over the full disc of the planet. 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. [69] The following conversation occurred between two operators of the American Telegraph Line between Boston and Portland, Maine, on the night of 2 September 1859 and reported in the Boston Traveler: Boston operator (to Portland operator): "Please cut off your battery [power source] entirely for fifteen minutes."
