Daichi Hiramatsu, Jamison Burke, Iair Arcavi, D. Andrew Howell, Curtis McCully, Stefano Valenti report/s a classification of object: SN 2019dkx

Type: SN Ia
Redshift: 0.06

Remarks: Using Superfit (Howell et al. 2005, ApJ, 634, 1190) and SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find good fits to several normal Type Ia SNe about a few days before maximum at an inferred redshift of 0.060 (no host redshift measurements available on NED). The apparent r-band magnitude reported by ZTF upon discovery on 2019-04-10 08:20:00 was 18.9, corresponding to a MW extinction corrected absolute magnitude of -18.3. which is consistent with the Ia classification and its phase. We measure a Si II 6355 velocity of -11,000 km/s.

The following Classification spectrum was provided:
