3C 371is aBL Lac object[1][2]located in theconstellationDraco.With aredshiftof 0.051,[2]thisactive galaxyis about 730 millionlight-yearsaway.[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 emissionfrom 3C 371 was first detected in ground-based images by Nilsson et al. in 1997, and confirmed withHST(Scarpa et al.) in 1999.[4]The impliedviewing anglemay be less than 18 degrees.[4]But nosuperluminal motionhas been detected, despite frequent monitoring by theVery 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]
