We report the classification of AT2022dek from spectroscopic observations with the Goodman spectrograph on the Southern Astrophysical Research (SOAR) telescope, made on 2022 Mar 10 UT. The target was supplied by PSST. The classification was performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
PS22boc | AT2022dek | 10:25:01.413 | +01:53:02.74 | 0.080 | Ia | 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) We measure a Si II 6355 velocity of -10,700 km/s.
