We report the classification of AT 2019yyb from spectroscopic observations with the Goodman spectrograph on the Southern Astrophysical Research (SOAR) telescope. The target was supplied by ATLAS. The observation was made on 2019 Dec 31 UT. The classification was performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024). We thank the SOAR staff and the director, Jay Elias, for helping with this target-of-opportunity observation under NOAO program 2019B-0250.
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
ATLAS19beri | AT2019yyb | 09:03:48.87 | -05:34:00.55 | 0.068 | Ia | -4 d | (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 an Si II 6355 velocity of -11,600 km/s.
