The Nordic Optical Telescope (NOT) Unbiased Transient Survey (NUTS; ATel #8992) reports the spectroscopic classification of SNe 2017jzp and 2018bf in host galaxies KUG 1326+679 and SDSS J225746.53+253833.5, respectively.

The observations were performed with the 2.56 m Nordic Optical Telescope equipped with ALFOSC (range 350-950 nm; resolution 1.6 nm FWHM) on 2018-01-12 UT.

Survey Name    | IAU Name   | Discovery (UT)  | Discovery mag | Observation (UT) | Redshift | Type | Phase      | Notes  
Gaia18ack      | SN2017jzp  | 2017-12-19.6    | 18.74         | 2018-01-12       | 0.055    | Ia   | post-max   | (1)  
ATLAS18abb     | SN2018bf   | 2018-01-01.2    | 18.79         | 2018-01-12       | 0.025    | Ic   | around max | (2)  

(1) Redshift from host (NED/SDSS) and agrees with that from SN features. Spectrum agrees with those of SNe Ia few days to weeks after maximum light.
(2) Redshift from host-emission lines and agrees with that from SN features. Spectrum agrees with those of SNe Ic around maximum light.

Classification(s) was(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.
