The Asiago Transient Classification Program (Tomasella et al. 2014, AN, 335, 841) reports the spectroscopic classification of ASASSN-16jj (SN 2016flu) in SDSS J234711.91+100459.

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

ASASSN-16jj | SN 2016flu  |SDSS J234711.91+100459|2016-08-27 13:40:47|     17.1      | 2016-08-27.87    |    0.034  | SN Ia  |  before max  | (1) 

(1) The best match is with the Type Ia SN 2003du and SN 2003kf about one week before B-band maximum light. Using the redshift 0.034 (suggested by SNID), from the position of the minimum of the Si II 635nm feature, we infer an expansion velocity of ~12600 km/s for the ejected material.

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. The Asiago classification spectra are posted at the website http://sngroup.oapd.inaf.it.
