QSO B1038+528A, also known as OL 564, is a radio-loud quasar located in the constellation of Ursa Major. The redshift of the quasar is (z) 0.678 and it was first discovered via a NRAO interferometer survey by a team of astronomers lead by F.N. Owen in 1980, who described it along with QSO B1038+528B as an extremely close pair of quasars. The radio spectrum of the quasar is considered as flat, making it a flat-spectrum radio quasar.
