Coolcoulaghta Cairn: Luni-solar rises

East centred view with luni-solar trajectories c.1200BCE from Coolcoulaghta Cairn, West Cork, Ireland. Summer cross-quarters are on the end of the local ridge. The lunistice range starts at an intersect dip and also ends at one, with summer solstice rising from a hilltop in the middle. Equinox sunrise is on a distant peak with its half-month brackets on a nearer top and at a sea intersect over the end of this hilltop. Half-way to the summer cross-quarters is in a dip and half-way to the winter cross-quarters is in a bay of the sea. Winter cross-quarters are at a land / sea intersect with minor standstills on the other side of the same bay. The lunistice zone then runs along the final peninsula of the mainland.
