TNS Classification Report No. 16492 [ 2024TNSCR.316....1S ]
Date Received (UTC): 2024-02-01 00:05:53 Sender: Giorgio Valerin
Group: Padova-Asiago
I. Salmaso (INAF OAPd, Unipd), G. Valerin (INAF OAPd), F. Guidolin (Unipd) report/s a classification of object: SN 2023sil
Type: SN IIRedshift: 0.03755
Remarks: 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.
The following Classification spectrum was provided:
Obsdate: 2024-01-31 21:40:00
Instrument: AFOSC
Telescope: Asiago Ekar Telescope
Remarks: Spectrum obtained with the Asiago 1.82m Copernico Telescope equipped with AFOSC and VPH7. There is residual host contamination.
