Spectacular Aurora Borealis Lights Up the Cork Night Sky

Not often seen in Ireland, the phenomenon creates a stunning array of colours in the night sky. Met Éireann said: The colour of the northern lights will change due to the type of gas particles that are colliding. "Oxygen molecules at approximately 100km above the earth produce a greenish-yellow colour, while a red aurora can be seen when high level oxygen molecules are involved. "Blue or purple auroras indicate the presence of nitrogen molecules." The forecaster added that the best places to see the northern lights in Ireland are locations with very small amounts of light pollution. Parts of the west and north coast would offer the greatest chance of seeing the display, it added.
