Andrew Howell, Curtis McCully, Megan Newsome, Estefania Padilla Gonzalez, Joseph Farah Global SN Project SN II 0.006 1 Global SN Project The spectrum shows prominent P-Cygni profiles from the Balmer series, consistent with a young SN Type II. From the position of the minimum of H beta we measure an expansion velocity of ~12000 km/s. From the narrow emission superimposed to the main profile, we measured a redshift of 0.006, confirming the association with the host galaxy NGC 7421. 2023TNSCR3376....1T
