With a redshift of 0.051,[2] this active galaxy is about 730 million light-years away.[3] 3C 371 is a well known object, first associated with the BL Lac class by Miller in 1975,[4] and is among the nearest and brightest BL Lacs.[4] Optical jet emission from 3C 371 was first detected in ground-based images by Nilsson et al. in 1997, and confirmed with HST (Scarpa et al.) in 1999.[4] The implied viewing angle may be less than 18 degrees.[4] But no superluminal motion has been detected, despite frequent monitoring by the Very Long Baseline Array (VLBA).[4] There are photos of this object dating back to 1895, and they suggest that this objects magnitude can vary by ±1.5.[5] References1. ^1 2 3 4 5 {{cite simbad |title=3C 371 |accessdate=2010-04-11}} 2. ^1 2 3 4 {{cite web |title=NASA/IPAC Extragalactic Database |work=Results for 3C 371 |url=http://nedwww.ipac.caltech.edu/cgi-bin/nph-objsearch?objname=3C+371&img_stamp=yes&extend=no |accessdate=2010-04-11 }} 3. ^1 2 {{cite web |date=2008-01-11 |title=3C 371 |publisher=XJET: X-Ray Emission from Extragalactic Radio Jets |url=http://hea-www.harvard.edu/XJET/source-d.cgi?3C_371 |accessdate=2010-04-11}} 4. ^1 2 3 4 5 {{cite journal |last=Perlin |first=Eric S. |author2=Padgett |author3=Georganopoulos |author4=Sparks |author5=Biretta |title=Optical Polarimetry of the Jets of Nearby Radio Galaxies.
