The SN redshift is consistent with the redshift of ESO 448- G 008 at z= 0.023590 (138 Mpc). The SN is 60 arcseconds from the host nucleus, which corresponds to a physical distance of 40 kpc. Another possibility is that the SN host galaxy is fainter than the detection limit of Pan-STARRS images, corresponding to M > -14.3 mag at z ~ 0.03.
