At the Giant’s Causeway, Co Antrim.

By Martin McKenna, who sez:

The aurora we saw was sublime!, the best I have seen here since 2005 with vertical green pillars of light some 60 degrees high accompanied by amazing pulsating/flaming motions like the beating of a heart which was jaw dropping. We could even see the beams reflecting on the ocean forming their own glitter paths – what a night!! Canon 450D, 18mm, ISO1600
