The NOT Unbiased Transient Survey (NUTS; ATel #8992) collaboration reports the spectroscopic classification of supernova SN 2017faa (= ATLAS17hpc, Gaia17bvj) in host galaxy IC 4224.

The observations were performed with the 2.56 m Nordic Optical Telescope equipped with ALFOSC (range 350-950 nm; resolution 1.6 nm) on 2017-07-22.9 UT.

Survey Name                | IAU Name   | Discovery (UT)  | Discovery mag | Observation (UT) | Redshift | Type | Phase          | Notes  
ATLAS17hpc, Gaia17bvj      | SN 2017faa | 2017-06-27.3    | 16.81         | 2017-07-22.9     | 0.018    | II   | post-maximum   | (1)  

(1) Host redshift from NED (SDSS DR1). Good spectral match is obtained with spectra of several type II SNe at around one week 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.
