We report the following classifications of optical transients from spectroscopic observations with the Kast spectrograph on the Shane telescope. Targets were supplied by KAIT and ATLAS. All observations were made on 2018 Nov 3 UT. Classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
KAIT-18az | AT2018hsi | 19:21:10.30 | +43:56:33.36 | 0.054 | Ia-91bg | few days after peak | 1
ATLAS18xuk | AT2018hob | 06:17:39.25 | -25:25:01.12 | 0 | CV | |
Notes: (1) Redshift is derived from the host galaxy. Best SNID match is to Ia-91bg SN 2007al +10 days after maximum but there are also very good matches to SNe Ia-91bg at +2-3days. We measure a Si II 6355 velocity of -8,500 km/s.
