    • n aurora In electricity, an electric glow-discharge, appearing at very high voltages and some what resembling the aurora borealis. It first appears as a blue glow at surfaces and especially at points; at higher electric pressures or voltages pink streamers issue, which gradually lengthen with increasing voltage until ultimately a disruptive spark occurs. See electric spark. Also called corona.
    • n aurora The length of time elapsing between successive maxima or minima of auroral displays, as the diurnal, the annual, the sun-spot, and the 55-year period. The last is possibly equivalent to 5 sun-spot periods. See auroral periodicity.

Sequences of Numbers Involved in Unsolved Problems
The South Pole and Dome F lie nearly under the auroral circle, so suffer frequently, whereas Domes A, B & C lie just 6◦ from the geomagnetic South Pole, so that aurorae there generally lie below the horizon.
Astronomy in Antarctica
Aurorae will therefore only impact on a small subset of observations that might be undertaken from Antarctica.

According to our estimates, fluorescent x-ray emission excited by solar x-rays, even during flares from the active Sun, charge-exchange processes, previously invoked to explain Jupiter’s x-ray aurora and cometary x-ray emission, and ion stripping by dust grains fail to account for the observed emission.
Discovery of Soft X-Ray Emission from Io, Europa and the Io Plasma Torus
Charge exchange processes have been invoked to explain Jupiter’s x-ray aurora (Cravens et al. 1995, Bhardwa j & Gladstone 2000) and x-ray emission from comets (Cravens 1997, Dennerl 1999).

X-rays this way. Recent observations (Branduardi-Raymont et al., 2006a) have shown that bremsstrahlung X-rays are being produced in the Jovian aurora with photon energies in excess of a keV, although the total power is much less than the soft X-ray power produced in line emission.
