The Asiago Transient Classification Program (Tomasella et al. 2014, AN, 335, 841) reports the spectroscopic observation of ASASSN-15cq in CGCG 218-7 (ATel #7035). The observation was performed with the Asiago 1.82m Copernico Telescope (+AFOSC; range 340-820 nm; resolution 1.4 nm), equipped with the CCD Andor IKON L936.

ASASSN-15cq                   |  20150210.02 |  0.0273    |  SN Ia      | at max    | (1)      

(1) The expansion velocity of the ejected material, as inferred from the position of the absorption of the Si II 635.5 nm line is about 10900 km/s. The host galaxy redshift is from SDSS4, 2005 (via NED).

Classification was done with GELATO (Harutyunyan et al. 2008, A&A, 488, 383) and SNID (Blondin and Tonry 2007, ApJ, 666, 1024). The Asiago classification spectra are posted at the website http://sngroup.oapd.inaf.it.
