Claudio Balcon (Belluno A.O. ISSP) report/s a classification of object: SN 2022ds
Type: SN IaRedshift: 0.017679
Remarks: GELATO (Harutyunyan et al., 2008, A&A, 488, 383) and DASH (Muthukrishna et al., 2019, ApJ, 885, 85) suggest that this spectrum resembles that of SN Type Ia 6-10 days before the maximum at the redshift of the host galaxy (value from NED).
The following Classification spectrum was provided:
Obsdate: 2022-01-08 22:12:00
Instrument: Other
Telescope: Other
Remarks: I obtained the low-resolution spectrum R~100 using the FOSC-ES32 spectrograph attached to a 0.2m telescope, in the course of Italian Supernovae Search Project.
