22221 2025-10-15 08:56:24 Hrishav Das Hrishav Das (IIA), Avinash Singh (Stockholm University), G.C. Anupama (IIA), D.K. Sahu (IIA) None SN 0.042 1 We classify SN 2025aada as a young SN based on follow-up spectra obtained on JD 2460962.3 with the 2 m HCT at IAO, Hanle. The source is non-nuclear, and the spectrum exhibits a blue continuum with a narrow Halpha emission feature, likely originating from the bright host galaxy at a redshift of z ~ 0.042. The source has an absolute magnitude of ~ –17 mag, based on the latest reported photometry, consistent with an early phase SN. Spectral cross-matching with GELATO indicates the best match with Type II SN 1999gi at approximately 3.8 days after explosion, although the Balmer emission features are less prominent in our spectrum. 2025TNSCR4139....1D
