Guidolin (Unipd) Padova-Asiago SN II 0.03755 1 Padova-Asiago Hydrogen rich spectrum, SN 1987A-like light curve. The spectrum shows that AT 2023sil is a Type II SN. The Hα and Hβ lines present a P-Cygni profile, with the absorption minimum at about -6000 km/s and -5000 km/s from rest wavelength, respectively. The w-band light curve collected by Pan-STARRS shows a double peak, which suggests a 1987A-like event. 2024TNSCR.316....1S
