C. Angus, P. Aleo report/s a classification of object: SN 2023ocx
Type: SN Ia-CSMRedshift: 0.076
Remarks: Spectrum taken with ALFOSC/NOT in gr4 on 19/09/2023. Spectrum matches templates of late time (>+20d) SNe Ia, with H emission superimposed. z=0.076 found from host galaxy lines. The prolonged peak of the light curve post-max in r-band (plateauing for ~30 days), combined with the H-alpha emission suggest a Ia-CSM classification. Template comparisons were done using superfit and SNID.
The following Classification spectrum was provided:
