We report the discovery of a bright quasar (E = 15.8, z = 0.868) associated
with the flat-spectrum radio source NVSS J235953 - 124148. This quasar, wh
ich we designate QSO 2359 - 1241, possesses a rare combination of extreme p
roperties that make it of special interest. These properties include intrin
sic high-velocity outflow seen in absorption for both high- and low-ionizat
ion species, high optical polarization (similar to5%), significant radio em
ission, and dust reddening. The dereddened absolute magnitude of QSO 2359 -
1241 places it among the three most optically luminous quasars known at z
< 1. High-resolution spectroscopy and a detailed analysis of the optical/ul
traviolet absorption features will be given in a companion paper.
