Someone smart!!!!!Auroras: what is the difference between the southern and northern lights?

I'm not claiming to be smart...



The aurorae are virtually the same; the only difference being their origins...



The Aurora Borealis (Northern Lights) happen around the north magnetic pole of the Earth, and Aurora Australis (Southern Lights) occur around the Earth's south magnetic pole.



They both occur because of the Earth's magnetic fields' reaction to the solar wind; electrically charged particles eminating from the Sun, most often caused by sunspots.



These occurences happen more frequently during a period of 'solar maximum', when the Sun is most magnetically active, a cycle that happens every 11 years, on the average.

They are the same thing. The only difference is that one occurs in the southern hemisphere and one occurs in the northern hemisphere.

Their location. Period.
One is found on the northern hemisphere, the other on the southern. North = aurora borealis, south = aurora australis.



Both are formed from the same phonemenon:charged particles collide with the earth's atmosphere. The collisions in the atmosphere electronically excite atoms and molecules in the upper atmosphere. The excitation energy can be lost by light emission or collisions.
