Aurora Borealis (northern lights) and Aurora Australis (southern lights); aurora polaris (polar lights), is a general name for both. Both northern and southern lights are formed the same way and at the same time in perfect symmetry
     Aurorae occur when charged particles from the Sun (solar wind) collide with atoms and molecules in our atmosphere (atmospheric gases are disrupted by these electrically charged particles from the Sun). Lightning is the result of similar happenings.
    The downward flow of particles from the Sun causing the Northern and Southern Lights is matched by an equal yet opposite flow of electrons upward. That flow carries the return current of what essentially is a giant circuit. This upward flow hollows out electrons in regions of the Earth's ionosphere and produces black auroras. 
    The black aurora is the flip side of the Northern and Southern Lights. They are the opposite of visible auroras. "They are a perfect mirror image. They are two opposite sides of the exact same phenomenon," said Goran Marklund of the Alfven Laboratory in Sweden to the American Geophysical Union, as recorded in the journal Nature, and The Calgary Herald.
    Solar wind has been measured at 200 to 500 miles per second by astronauts orbiting earth. Solar wind from our Sun reaches as far as Neptune.
    Solar wind particles-(plasma) are miniature magnets (photons – hot ionized gas comprised of protons, helium and electrons, which are charged particles from the Sun) carrying part of the Sun's magnetic field with them as they flow from it in vast clouds that pummel Earth's magnetic field. Most of the time these are deflected by the Earth's magnetic field, but sometimes they penetrate. These particles are funneled to open points in the Earth's magnetic field at the north and south poles where they react with the Earth's atmospheric gases (oxygen and nitrogen), creating the north and south auroras.
    Jo Ann Joselyn, senior space scientist at the Space Environment Centre, the space counterpart to the National Weather Service, and Bruce Tsurutani, a physicist with NASA's Jet Propulsion Laboratory, are producing a research paper about how solar storms can affect Earth. ... Astronomy Magazine, January, 2000, page 56. They have found that Northern Lights appear more often when the sun is the most active, right around the peak of the solar cycle.-...continues
