We report the classification of AT2021cta from spectroscopic observations with the Kast spectrograph on the Shane telescope. The target was supplied by ALeRCE (selected from the ZTF data stream). All observations were made on 2021 Feb 19 UT. The classification was performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
ZTF21aakildf | AT2021cta | 08:41:26.877 | +44:08:46.42 | 0.081 | Ia | -5 | (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 -12,500 km/s.
