redshift
In physics, a redshift is an increase in the wavelength, and corresponding decrease in the frequency and photon energy, of electromagnetic radiation (such as light). The opposite change, a decrease in wavelength and simultaneous increase in f ...

3C 371 is a well known object, first associated with the BL Lac class by Miller in 1975, and is among the nearest and brightest BL Lacs.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. The implied viewing angle may be less than 18 degrees. But no
superluminal motion
In astronomy, superluminal motion is the apparently faster-than-light motion seen in some
radio galaxies, BL Lac objects, quasars, blazars and recently also in some galactic sources called microquasars. Bursts of energy moving out along the rel ...
has been detected, despite frequent monitoring by the Very Long Baseline Array (VLBA).
There are photos of this object dating back to 1895, and they suggest that this objects magnitude can vary by ±1.5.
