Foley (UCSC) UCSC SN II 0.0247 1 UCSC The spectrum has two strong absorption features near the wavelength of H-alpha. The redder feature is consistent with photospheric H-alpha P-Cygni absorption at -8,000 km/s. The bluer component is consistent with either high-velocity H-alpha absorption at -17,500 km/s or a strong Si II absorption at -8,000 km/s. ATel: 15353 2022TNSCR1163....1T
