Editing Summer Triangle (section)

==History==
The term was popularized by the American author [[H. A. Rey]] and the British astronomer [[Patrick Moore]] in the 1950s.<ref name=moore>{{cite book|author=Patrick Moore|title=Patrick Moore's History of astronomy|url=https://books.google.com/books?id=HXTvAAAAMAAJ|date=20 October 1983|publisher=Macdonald|isbn=978-0-356-08607-1}}</ref> The name can be found in constellation guidebooks as far back as 1913.<ref>Alice Mary Matlock Griffiths (1913), ''The Stars and Their Stories: A Book for Young People''.</ref> The Austrian astronomer [[Oswald Thomas]] described these stars as ''Grosses Dreieck'' (Great Triangle) in the late 1920s and ''Sommerliches Dreieck'' (Summerly Triangle) in 1934.  The asterism was remarked upon by [[Joseph Johann von Littrow]], who described it as the "conspicuous triangle" in the text of his atlas (1866), and [[Johann Elert Bode]] connected the stars in a map in a book in 1816, although without a label. These are the same stars recognized in the Chinese legend of ''[[The Cowherd and the Weaver Girl]]'', a story dating back some 2,600 years, celebrated in the [[Qixi Festival]]. The stars also bear ceremonial significance in the related celebrations of [[Tanabata]], [[Chilseok]], and Thất Tịch, derived from Qixi. In the mid- to late-20th century, before [[inertial navigation system]]s and other electronic and mechanical equipment took their places in military aircraft, the [[United States Air Force]] navigators referred to this asterism as the "Navigator's Triangle".<ref>{{cite book |author=Lt.
