[1] It was first discovered in 1983, by researchers who presented 114 objects in the Palomar-Green bright quasar survey, as one of the best studied samples of active galactic nuclei (AGN).

The quasar shows a blueshift of the [O III] 5007 Å line that is 1150 km s−1 with respect to the systemic velocity of the galaxy as well as the blue asymmetry of its profile.

[5] The large [O III] blueshift or so-called 'blue outliers' by researchers, is found theoretically interpreted by the result of intense outflows whose receding parts are obscured by an optically thick accretion disc[6] or possibly a scenario which the narrow-line region clouds are entrained by decelerating winds, potentially associated with the high Eddington ratio typical of the 'blue outliers'.

The photoionization models indicate that the nitrogen-to-silicon relative abundance is solar, yet magnesium is found underabundant by a factor of ≈2.

By extracting out its rotational curve and reporting emission-line spectroscopy of the nearby galaxy, researchers suggests the metallicity is ≈8× higher compared to [N/H] in the absorber.
