The Asiago Transient Classification Program (Tomasella et al. 2014, AN, 335, 841) reports the spectroscopic observation of ZTF20aamxhlg (AT 2020ckt).
The target was supplied by ALeRCE using the public ZTF stream and reported in the Transient Name Server (TNS).
The observation was performed with the Asiago 1.82m Copernico Telescope (+ AFOSC; range 340-820 nm; resolution 1.4 nm).

The spectrum is consistent with those of SN Ia before maximum. The redshift is deduced from the position of the narrow Halpha emission line of the host galaxy (z=0.066). Using this redshift, an expansion velocity of about 10000 km/s is derived from the SiII 635.5 nm.
The classification was performed using the GELATO (Harutyunyan et
al. 2008, A&A, 488, 383)
and SNID (Blondin and Tonry 2007, ApJ,
666, 1024) tools.
