The constellation of Corona Austrina describes an arc with seven or eight stars just south of Sagittarius. The constellation is the opposite of "Corona Borealis", seen around the zenith of night sky in the early summer.
Although the Corona Austrina is a little smaller than the Corona Borealis, the constellation has the altitude of meridian transit of only 20 degrees or so at around Tokyo. So the apparent size of the Corona Austrina looks fairly large.
The constellation has neither major legends nor myths, but unexpectedly has long history that it was listed in the Ptolemaic constellation in the beginning of AD.
