We report the classifications of AT2022pje and AT2022rge from spectroscopic observations with the LRIS spectrograph on the Keck I telescope, made on 2022 Aug 22 UT. The targets were discovered with Pan-STARRS, with AT2022rge being supplied by YSE. The classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
PS22ggm | AT2022pje | 21:24:12.06 | +08:56:13.99 | 0.099 | Ia | +15d |
PS22hba | AT2022rge | -06:33:42.97 | +19:58:33.77 | 0.06 | Ia-SC | peak | (1)
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) The spectrum is blue with strong C II absorption similar to "super-Chandrasekhar" SNe Ia.
