An unknown object at the position R. A. 13h 36m 04s Dec. -10 deg 21 min 05 sec (1950) is studied. It may be a compact galaxy with an unusual jet with a nonthermal spectrum and at the same time with the presence of emission lines in the spectrum. The suggested 'jet' is seen at a distance of about 20 arcsec (approximately 9.0 kpc) out of the image of the host galaxy, the angular diameter of which is a bout 10 arcsec. It may also be that in this case we observe a pair of galaxies: a compact one and an edge-on spiral. The latter version seems to be true. The redshift of the object is z = 0.0241. The redshift of the jet (or of the edge-on spiral) is slightly, by about 200 km/s, less than that of the compact galaxy, and thus the jet (if the observed feature is a jet) is almost perpendicular to the line of sight. The linear size of the compact galaxy is less than 5 kpc, its absolute stellar magnitude is about -17m. Thus this galaxy is a dwarf one. If the jetlike feature is also a galaxy then its extent is about 18 kpc.
