The Nordic Optical Telescope (NOT) Unbiased Transient Survey (NUTS; ATel #8992) collaboration reports the spectroscopic classification of ASASSN-17ia (SN 2017ewv) in the host galaxy UGC 08287. The target was detected by the All-Sky Automated Survey for Supernovae (ASAS-SN) at V = 16.9 mag on UT 2017-06-23.31. The object had not been detected in ASAS-SN images taken on 2017-06-09.33 and before.

The observation was performed with the 2.56 m Nordic Optical Telescope equipped with ALFOSC on 2017-06-25.9 UT (range 350-950 nm; resolution 1.6 nm).

 
Name         |  IAU Name   |  Redshift  |  Discovery (UT) |  Discovery mag  |  Type  | Phase            | Notes 
ASASSN-17ia  |  SN 2017ewv |  0.022516  |  2017-06-23.31  |  16.9           |   IIP  | about a week old | (1) 

(1) Good matches are obtained using SNID with spectra of the Type IIP SNe 2004et and 2006bp obtained some days to a week after explosion. The redshift is obtained from the NED.

Classification was performed using the SNID (Blondin and Tonry 2007, ApJ, 666, 1024) tools.
