The name of the constellation was entered as "Corona Australis" when the International Astronomical Union (IAU) established the 88 modern constellations in 1922. In 1932, the name was instead recorded as "Corona Austrina" when the IAU's commission on notation approved a list of four-letter abbreviations for the constellations. The four-letter abbreviations were repealed in 1955. The IAU presently uses "Corona Australis" exclusively.
