The Asiago Transient Classification Program (Tomasella et al. 2014, AN, 335, 841) reports the spectroscopic classification of AT2016ajo, discovered by Y. Ding, W. Gao and X. Gao in an anonymous galaxy near UGC 11344.

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

(1) A good match is obtained with a spectrum of the Type Ib SN 2009iz taken about 3 weeks after the maximum light. From the position of the minimum of the broad He I absorption lines, we infer an expansion velocity of about 8000 km/s.

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