Hanin Kuncarayakti (U. Turku), Keiichi Maeda (Kyoto U.), Anjasha Gangopadhyay, Avinash Singh (Stockholm U.) report/s a classification of object: SN 2024lhs
Type: SN IIRedshift: 0.037
Remarks: The spectrum shows a bump at Halpha wavelength, indicating a possible Type II SN. The light curve evolution appears to be quite fast, which may indicate an initial cooling emission associated with SNe II. At the assumed redshift (z = 0.037 from host emission lines), the observed peak magnitude of around 19 mag corresponds to an absolute magnitude slightly fainter than -17 mag if without extinction.
