Piscis Austrinus is a constellation bordered by Capricornus to the northwest, Microscopium to the southwest, Grus to the south, Sculptor to the east, and Aquarius to the north. Its recommended three-letter abbreviation, as adopted by the International Astronomical Union in 1922, is "PsA".[3] Ptolemy called the constellation Ichthus Notios "Southern Fish" in his Almagest; this was Latinised to Piscis Notius and used by German celestial cartographers Johann Bayer and Johann Elert Bode.[4] Bayer also called it Piscis Meridanus and Piscis Austrinus, while French astronomer Nicolas-Louis de Lacaille called it Piscis Australis. English Astronomer Royal John Flamsteed went with Piscis Austrinus, which was followed by most subsequently.[5] The official constellation boundaries, as set by Belgian astronomer Eugène Delporte in 1930, are defined by a polygon of four segments (illustrated in infobox). In the equatorial coordinate system, the right ascension coordinates of these borders lie between Àtụ:RA and Àtụ:RA, while the declination coordinates are between −24.83° and −36.46°.[6] The whole constellation is visible to observers south of latitude 53°N.[7]Àtụ:Efn
