We report the following classifications of optical transients from spectroscopic observations with the Goodman spectrograph on the Southern Astrophysical Research (SOAR) telescope. Targets were supplied by the ATLAS. All observations were made on 2018 October 28 UT. Classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
ATLAS18xzc | AT2018how | 23:26:12.72 | -25:44:24.32 | 0.051 | Ia | +1 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) Good fits with SNe Ia 91T-like spectra at maximum light. We measure an Si II 6355 velocity of -10,100 km/s.
