Andrew Howell, Curtis McCully, Megan Newsome, Estefania Padilla Gonzalez, Giacomo Terreran Global SN Project SN Ib 0.015 1 Global SN Project The spectrum, obtained roughly two days after the initial ATLAS discovery, shows a blue continuum superimposed with several broad P Cygni features. From the narrow host H-alpha line we measure a redshift z=0.015. Assuming this redshift, the broad features are well matched by He I with absorption velocities of 14,000 km/s. Recent ZTF and ATLAS photometry show that the light curve is rising. Further follow-up is encouraged. 2023TNSCR1474....1P
