Flat-spectrum radio quasar
Type of highly variable quasar or subtype of blazar
Summary
A flat-spectrum radio quasar, also known as a optically violent variable quasar or OVV quasar, is a type of highly variable quasar. It is a subtype of blazar that consists of a few rare, bright radio galaxies, whose visible light output can change by 50% in a day. OVV quasars have essentially become unified with highly polarized quasars (HPQ), core-dominated quasars (CDQ), and flat-spectrum radio quasars (FSRQ). At visible wavelengths, they are similar in appearance to BL Lac objects but generally have stronger broad emission lines.

rearrange lead names.
Alpha3031 moved page [[OVV quasar]] to [[Flat-spectrum radio quasar]] over redirect: [[Special:Permalink/1323012182#DR3|Requested]] by Praemonitus at [[WP:RM/TR]]: Both names are valid and synonymous, but FSRQ is now the more common abbreviation employed in technical papers and OVV is becoming archaic usage. [Looks about right to me]

Added another example, I believe, according to the article of that galaxy.
FSRQ more common than OVV
