Michael Rich (UCLA) ZTF SN Ia 0.061179 1 1 ZTF Spectrum is fit by template spectra from previously classified SN Ia and Ic events, with the silicon absorption feature from SN Ia events providing the best fit to the absorption trough between a rest wavelength of 5900Å and 6400Å. Redshift of z = 0.061179 ± 0.000009 from SDSS DR13. Classification performed using Next Generation Superfit (NGSF, Goldwasser et al. 2022). 2025TNSCR.865....1W
