6229 Tursachan           Discovered 1983 Nov. 4 by B. A. Skiff at the Anderson Mesa Station of the Lowell Observatory.
The name is "Standing Stones" in Gaelic, a term used to refer to the stones placed during neolithic times into groups---often circles---throughout the British Isles. Many of these arrangements exhibit astronomical alignments and may have been used to track the progression of seasons and mark the occurrence of other significant astronomical events. The name was suggested by Alice Cathryne Dennis, a seventh-grade student at The Mountain School in Flagstaff, Arizona, as winner of a contest to name this minor planet in conjunction with the 1997 Flagstaff Festival of Science. Citation prepared by C. B. Luginbuhl.
