3C 371 is a BL Lac object [1] [2] located in the constellation Draco. 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]
