Auroras are caused by radiation from the sun, called solar wind, interacting with Earth's magnetic field. When magnetic storms occur on the Sun, electrically charged particles (ions) from the corona and solar flares are added to the solar wind produced by the corona. Solar charged particles from the sun, which are normally radiated into space, sometimes get caught in the Earths magnetic field as they come into the upper atmosphere they react with other gases and produce coloured lights.
The Earth's magnetic field funnels particles from the solar wind over the polar regions (due to the magnetic nature of the Earth). The charged particles are accelerated by the Earth's magnetic field and interact with the gases in the upper atmosphere and cause the gas molecules to emit light. Electrons in the molecules are excited to higher energy levels by the accelerated charged particles and the electrons release photons when they fall back to lower energy levels.
When the ions from the sun first collide with air particles more than 80 kilometres above the ground, each causes a different reaction, and each reaction causes a different color to explode. Collisions of these particles with atmospheric molecules causes energy emission as visible light. Neutral nitrogen particles will create a purplish pink color, while ionic nitrogen transforms into a brilliant blue. If an ion crashes into oxygen in a lower altitude, it becomes the most common aurora, a yellowish-green color. If it however, collides with oxygen at a high level, it will create the rarest blood red aurora. An aurora is sometimes accompanied by a crackling sound. Auroras can occur on other planets.

Solar wind causes auroras because atoms go through water droplets in clouds. They act as prisms (the raindrops) and this causes the billowing, beautiful Aurora Borealis.
Yes, the Latin name for 'Northern Lights' is Aurora Borealis.
The rarest color for an Aurora Borealis is purple and orange in the aurora australis

Yes, the Auroras Borealis and Australis are real colored light displays in the sky, caused by solar storm particles colliding with atoms of oxygen and nitrogen in the upper atmosphere.

bit of a silly question really as you put the question under the heading which is your answer. Aurora Borealis and Aurora Australis
the best place to see auroras is either Canada or northern Alaska and Greenland
There are no hard and fast limits. Auroras have been seen anywhere in the USA except Hawaii.
It would be quite unusual to see auroras as far south as Kentucky, but it has happened; at the peak of the last sunspot cycle, there were auroras in Florida!
Auroras are usually confined to arctic (and antarctic) regions near the magnetic poles. The Philippines is a tropical nation. It would be extremely unusual for auroras to be visible in the Philippines.
Auroras. In the north, they are the Aurora Borealis, and i the south they are Aurora Australis.
