The Asiago Transient Classification Program (Tomasella et al. 2014, AN, 335, 841) reports the spectroscopic classification of ASASSN-16bn (also known as SN 2016adn), discovered by the All Sky Automated Survey for SuperNOvae (ASAS-SN) in 2MASX J03103162+0416184.

The observation was performed with the Asiago 1.82 m Copernico Telescope (+AFOSC; range 340-820 nm; resolution 1.4 nm), remotely controlled from the Padova Observatory.

Name             | Discovery UT     | Obs. Date UT |z         |   Type   | Phase          |Notes 
ASASSN-16bn      |20160209.24       | 20160211.73  |0.023166  |   Ia     | around max     | (1)  

(1) This is a type Ia SN around the maximum light, in agreement with the classification reported in Atel #8674 and #8680. A good match is found with SN 2003du, 2 days after maximum. From the position of the minimum of the broad Si II 635.5 nm absorption, we obtain an expansion velocity of about 10600 km/s.

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 spectrum is posted at the website http://sngroup.oapd.inaf.it.
