The Asiago Transient Classification Program (Tomasella et al. 2014, AN, 335, 841) reports the spectroscopic classification of SN 2016eob. The transient was discovered by Leonini et al. 2016, TNS Astronomical Transient Report No. 3994, Italian Supernovae Search Project (ISSP), on UT 2016-08-03.11 in the galaxy UGC00005 (2 other supernovae exploded in this host: SN 2000da, SN 2003lq). ISSP reports a discovery magnitude of 16.53, and they do not detect the object in images taken on 2016, July the 2nd and before.

The observations were performed with the Asiago 1.82 m Copernico Telescope equipped with AFOSC (range 340-820 nm; resolution 1.4 nm) on UT 2016-08-03.95

 
Name          |  Host galaxy   |   Redshift  |  Discovery (UT) |  Discovery mag |  Type  | Phase  | Notes  
SN 2016eob    |   UGC 00005    |    0.024    |  2016-08-03.11  |      16.53     |   II   | +15d   | (1)  

(1) A good match is obtained with the Type II SN 1996W two weeks after explosion. From the position of the minimum of the Balmer lines, we infer an expansion velocity of ~11000 km/s for the ejected material.

In addition, photometric follow-up observations were obtained, which are somewhat in disagreement with the discovery report.

 
Obs. Date UT  | B mag (err)  | V mag (err)  | g mag (err)  | r mag (err)   | i mag (err)    
2016-08-04    | 19.13 (0.02) | 18.32 (0.03) | 18.41 (0.01) | 18.23 (0.03)  | 18.15 (0.04) 
 

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