Diego Farias (DARK\NBI), Charlotte Angus (QUB) on behalf of the Young Supernova Experiment report/s a classification of object: SN 2025cm report/s a classification of object: SN 2025cm
Type: SN IIRedshift: 0.03
Remarks: We report the spectroscopic classification of SN2025cm as a Type II SN. Based on the strong blue continuum, SN2025cm is a young core-collapse SN. At the redshift of the likely host galaxy (WISEA J032915.87-043240.8; z=0.035471), we associate a broad feature at ~6500 Å to H-alpha emission.
The following Classification spectrum was provided:
