We report the following classifications of optical transients from spectroscopic observations with the Kast spectrograph on the Shane telescope. Targets were supplied by ZTF and ATLAS. All observations were made on 2019 Aug 26 UT. Classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
ZTF19abqmpsr | AT2019oml | 03:00:20.27 | +18:44:37.05 | 0.033 | Ia | peak | (1)
ATLAS19szp | AT2019omy | 23:53:43.18 | +17:43:54.12 | | Galactic | | (2)
ZTF19abrsssx | AT2019ons | 21:54:05.05 | -16:09:34.28 | 0.037 | Ia | -8 d | (3)
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 -10,800 km/s. (2) Blue continuum with Balmer emission lines at z = 0. (3) We measure an Si II 6355 velocity of -16,500 km/s.
