Stargazing in Cork, Ireland

Cork's Bortle 6 skies clear quickly heading west into rural County Cork and the Beara Peninsula, where Bortle 3 darkness is common. The Mizen Head and Sheep's Head areas offer some of Ireland's darkest accessible coastline. At 51.9°N, Cork sits a little south of Dublin but still catches the aurora during stronger Kp 5+ storms, with the dark Atlantic horizon to the south and west helping. Ireland's maritime climate brings frequent cloud, but post-frontal clearances off the Atlantic are often exceptionally transparent.
