The Asiago Transient Classification Program (Tomasella et al. 2014, AN, 335, 841) reports the spectroscopic observation of SN2017mf. The observation was performed with the Asiago 1.22-m Galileo Telescope (+ Boller & Chivens spectrograph).

 
Survey name | IAU name | Host galaxy | Disc. Date (UT) | Obs. Date (UT) | redshift | type |   phase    | notes  
 SN2017mf   | SN2017mf |  NGC 5541   |  2017-01-22.95  | 2017-01-23.04  |  0.0257  |  Ia  | before max |   1    

(1) Spectrum consistent with those of normal type Ia supernovae few days before maximum light, in agreement with the classification reported by Zhang et al (Atel #9986); we confirm the expansion velocity deduced from the absorption minimum of Si II 635.5 nm (about 10400 km/s)

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.
