Simon de Wet, Orapeleng Mogawana, David Buckely, Paul Groot report/s a classification of object: SN 2023mza
Type: SN IInRedshift: 0.0285
Remarks: AT2023mza was observed by the Southern African Large Telescope (SALT) on 2023 July 21 equipped with the Robert Stobie Spectrograph (RSS), employing the PG700 grating covering the wavelength range 4200-7400 Angstroms with a mean spectral resolution of 7.6 Angstroms. The spectrum shows strong Balmer emission lines at a common redshift of z=0.0285, equivalent to the redshift of the nearby spiral Galaxy ESO 239-12. The presence of strong Balmer emission lines are indicative of a circumstellar-medium interaction, so we classify AT2023mza as a supernova of type IIn. Observations are ongoing, and we encourage further photometric and spectroscopic follow-up.
The following Classification spectrum was provided:
Obsdate: 2023-07-21 22:46:14
