18022 2024-09-13 08:52:08 Avinash Singh Avinash Singh, Jesper Sollerman (OKC, SU) None SN II 0.019577 1 We classify SN 2024vfo as a Type II SN based on a follow-up spectrum obtained on 2024-09-13.08 UT with NOT/ALFOSC. The spectrum reveals a blue continuum along with broad P-Cygni Balmer features (Halpha, Hbeta and Hgamma) with an absorption trough at roughly 13,000 km/s, along with a feature of He II 4686 at a similar velocity. 2024TNSCR3488....1S

18019 2024-09-12 15:05:13 Moira Andrews Moira Andrews (UCSB/LCO), Joseph Farah, D. Andrew Howell, Curtis McCully None SN 0.019577 1 We report the classification of AT 2024vfo as a SN. The spectrum shows an almost featureless blue continuum with possible broad hydrogen lines at the host redshift (UGC 00690: z = 0.019577, d = 85.6 Mpc, value from NED). The spectrum peak is below our wavelength range (~3000 angstroms), indicating a temperature much greater than 10,000 K. 2024TNSCR3471....1A
