Aurora over Giant’s Causeway and Ballintoy Harbour, Co. Antrim

Gorgeous aurora captured by Martin McKenna! Last night’s geomagnetic storm (April 24, 2012) put on quite a show and this was not even a large event. This is near the childhood homes of some of our esteemed Irish solar physics colleagues!
