8679 Tingstäde           Discovered 1992 Mar. 2 at the European Southern Observatory in the course of the Uppsala-ESO Survey of Asteroids and Comets.
Tingstäde is a parish on Gotland. In Tingstäde Träsk, a swamp that is the second largest lake on the island, the remains of a timber construction involving some 10~000 logs, probably from the sixth century, is still visible on the lake floor.
