Corona Australis is located south of the Teapot in Sagittarius and follows the curved tail of Scorpius. Although it does not contain any particularly bright stars, it still has a distinctive shape of half an ellipse and lies on the edge of the Milky Way ribbon. The constellation area is 128 square degrees and the center culminates around midnight on June 30th. [9, 15]
The southern counterpart to Corona Borealis, the Northern Crown, has been known since the time of the Greek astronomer Ptolemy in the second century AD. One interpretation shows it to be the crown of the centaur Sagittarius. [7]
