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.
