O'Neill on behalf of GOTO collaboration GOTO SN Iax[02cx-like] 0.007438 1 Add GOTO The spectrum exhibits several narrow absorption lines in the blue, and is overall similar to the faint Iax SNe such as SN2020kyg. Template matches to the spectrum appear to be consistent with z~0.025 (as previously reported), but we consider this redshift unlikely. There is no clearly visible host underneath the bright foreground galaxy (z=0.007438, NED) in either PS or 2MASS, and the probability of chance alignment with this foreground galaxy is ~0.2%. Further, the narrow absorption lines are typically present in only the faint Iax SNe. At z=0.007438, the SN is fainter than -15mag, while at z=0.025 the SN would be -17.5, inconsistent with Faint Iax designation. 2025TNSCR.600....1P

Wavasseur (ICCUB) CET-3PO SN Iax[02cx-like] 0.025 1 1 CET-3PO Classification made with GELATO (Harutyunyan et al. 2008, A&A, 488, 383) shows a relatively good match with a SN Ia peculiar/02cx a few days before its peak. However, the redshift of the supernova (z~0.025) seems to differ from the host galaxy (z=0.007438, NED), suggesting that it may be located in a background galaxy. A further distance would also be more consistent with the current absolute magnitude of this supernova, which would be -16.5 mag at a distance of 110Mpc instead of -13.7 at 33Mpc. 2025TNSCR.568....1B
