WHAT CAUSES THE NORTHERN LIGHTS?
The Northern Lights are actually the result of collisions between gaseous particles in the Earth's atmosphere with charged particles released from the sun's atmosphere. Variations in colour are due to the type of gas particles that are colliding. The most common auroral color, a pale yellowish-green, is produced by oxygen molecules located about 60 miles above the earth. Rare, all-red auroras are produced by high-altitude oxygen, at heights of up to 200 miles. Nitrogen produces blue or purplish-red aurora.
BEST PLACES IN IRELAND TO SEE THEM?
Co. Donegal in Ireland is one of the best locations in the country due to it being far north with very dark clear skies. The Inishowen area in particular is an ideal perfect location and even if you don't see them we still have amazing dark skies full of stars. Best times of the year to have a chance to see them are from October to April, but you must have no cloud, no rain or snow and very little moon light with no light pollution from nearby towns and villages. A lot of luck is needed as well when looking for them.
