The NOT Unbiased Transient Survey (NUTS; ATel #8992) collaboration reports the spectroscopic classification of supernova SN 2017frc (= ATLAS17ixz) in host galaxy SDSS J162534.03+414058.7.

The observations were performed with the 2.56 m Nordic Optical Telescope equipped with ALFOSC (range 350-950 nm; resolution 1.6 nm) on 2017-08-31.9 UT.

 
Survey Name    | IAU Name   | Discovery (UT)  | Discovery mag | Observation (UT) | Redshift | Type | Phase                    | Notes  
ATLAS17ixz     | SN 2017frc  | 2017-07-03.4   | 18.99         | 2017-08-31.9     | 0.028    | II   | few weeks post-maximum   | (1)  

(1) SN redshift is consistent with that of the host (NED). Good spectral match is obtained with spectra of several type II SNe few weeks after maximum light.

Classifications were performed using the GELATO (Harutyunyan et al. 2008, A&A, 488, 383) and SNID (Blondin and Tonry 2007, ApJ, 666, 1024) tools. Calibrated spectra and additional information can be retrieved in the IAU Transient Name Server.
