We report the following classification AT 2020ctr from spectroscopic observations with the Kast spectrograph on the Shane 3-m telescope. The target was supplied ZTF via the ALeRCE broker. Observations were made on 2020 February 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
ZTF19aaklqod | AT2020ctr | 08:58:37.616 | +20:11:30.61 | 0.030 | Ia | -1 | (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 a Si II 6355 velocity of -10,700 km/s. We also measure a Na I D EW of 4.6 A.
