PKS 0208-512 is a blazar[1] located in the southern constellation of Eridanus. It has a redshift of 1.003[2] and was first discovered in 1975 by astronomers conducting the Parkes 2700 MHz survey in Australia as a bright astronomical radio source.[3] This object is also classified highly polarized[4] with the radio spectrum appearing to be flat, thus making it a flat-spectrum radio quasar.[5]
