We report the following classifications of optical transients from spectroscopic observations with the Kast double spectrograph on the Shane 3-m telescope at Mt. Hamilton, California. Targets were supplied by ZTF, ASASSN, and ATLAS. Observations were made on 2019 July 27 UT. Classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | IAU Name | RA (J2000) | Dec (J2000) | Type | z | Phase
ASASSN-19sj | AT2019ltw | 16:18:38.63 | +21:58:22.01 | IIb | 0.016 | 0
ATLAS19psi | AT2019lsu | 00:28:51.68 | -01:04:24.54 | Ia | 0.033 | -10
ZTF19abegzry | AT2019lnt | 22:36:55.95 | -22:13:15.37 | II | 0.033 | 5
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.
