Corona Australis (The Southern Crown)

Corona Australis (pronounced koʊˈroʊnə ɔːˈstrælɪs, -ˈstreɪ-) is the Latin name of a constellation situated south of the celestial equator. As such, it is more easily visible from the southern hemisphere.

In English language this constellation is also known as "The Southern crown" while in astronomical texts and literature this constellation is often abbreviated as "CrA" (according to the standard of the International Astronomical Union - IAU) or as "CorA" (according to a naming convention used by NASA).

The Latin genitive of the constellation name is "Coronae Australis" (pronounced koʊˈroʊniː ɔːˈstrælɪs) and it is used to identify some of the brightest stars in this constellation based on the Bayer or Flamsteed star naming convention. For instance: α Coronae Australis (the brightest star of Corona Australis based on the Bayer catalog); or 23 Coronae Australis (the 23th star in the constellation of Corona Australis based on the Flamsteed catalog).

Corona Australis is below the horizon from Greenwich, United Kingdom [change].
