The Asiago Transient Classification Program (Tomasella et al. 2014, AN, 335, 841) reports the spectroscopic classification of SN 2017A. The target was supplied by Duszanowicz and Tsinghua-NAOC (RANSSP).

The observations were performed with the Asiago 1.82 m Copernico Telescope equipped with AFOSC (range 340-820 nm; resolution 1.4 nm).

  
 IAU Name   | Host galaxy                 |   Redshift  |  Discovery Date | Discovery mag |  Classification  (UT) |  Type   | Phase    | Notes   
 SN 2017A   |  UGC 10104                  |    0.0328   |   2017-01-01.23 |      17.4     |   2017-01-24.19       |   Ia    |  +30d    | (1) 

(1) The AFOSC spectrum is similar to that of normal Type Ia, around one month after maximum light. The redshift of the host galaxy comes from Haynes et al. 1997, AJ, 113, 119, via NED.

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