Obsdate: 2025-04-22 09:33:49
Instrument: KAST
Telescope: 3m Lick Shane Reflector

Remarks: The spectrum of 2024zxj is most consistent with a phase of +70 using SNID, however the spectrum was taken approximately 135 days after peak. It shows a single emission feature with a broad component with FWHM ~ 8600 km/s, which we assume to be H-alpha at z = 0.11. We note that at a redshift of 0.11, the SN peaked at an absolute magnitude of R < -21 mag.
