We report the classifications of AT2023nwe and AT2023qxk from spectroscopic observations with the Kast spectrograph on the Shane telescope obtained on 2023 September 06 UT. The targets were supplied by PSST and ZTF respectively. The classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
PS23fqj | AT2023nwe | 21:45:24.628 | +01:34:20.91 | 0.194 | IIn | late | (1)
ZTF23ababkmo | AT2023qxk | 22:12:26.603 | +16:34:38.95 | 0.041 | II | pre-peak | (2)
Notes:
When the redshift is given to 2 decimal places, it is derived from the SN spectrum. Otherwise, the redshift is determined from the host galaxy.
(1) We measure a H-alpha FWHM of 500 km/s.
(2) We measure a H-alpha FWHM of 9700 km/s.
