Andrew Howell, Curtis McCully, Iair Arcavi (TAU) Global SN Project SN Icn 0.01948 1 Global SN Project The spectrum, obtained several days before peak brightness, shows a hot blue continuum dominated by narrow lines of highly-ionized C, including emission features of C III and C IV. It is most similar to the early-time spectra of the Type Icn SN 2021csp (Fraser et al. 2021, Perley et al. 2022). 2022TNSCR1233....1P
