We report the classification of AT2022inl and AT2022jdd from spectroscopic observations with the the Goodman spectrograph on the Southern Astrophysical Research (SOAR) telescope, made on 2022 May 3 UT. They were supplied by ATLAS and ALeRCE (selected from the ZTF data stream), respectively. Classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
ATLAS22nbj | AT2022inl | 10:56:59.422 | +02:36:42.93 | 0.0351 | II | max | (1)
ZTF22aaiugin | AT2022jdd | 15:02:45.389 | -15:48:11.36 | 0.12 | Ia | -4d |
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 an H-alpha absorption velocity of -10,400 km/s.
