Casares, L. Nuttall, B. Godson, A. Kumar on behalf of GOTO collaboration report/s a classification of object: SN 2025txi
Type: SN IaRedshift: 0.073954
Remarks: Good template matches obtained to SNe Ia around 1-2 weeks post-peak. Redshift corresponds to spectroscopic redshift of host galaxy, obtained via NED - also consistent with narrow host H and [S II] lines seen in spectrum.
The following Classification spectrum was provided:
Obsdate: 2025-08-30 04:44:08
Instrument: ALFOSC
Telescope: Nordic Optical Telescope
