The Nordic Optical Telescope (NOT) Unbiased Transient Survey (NUTS; ATel #8992) reports the spectroscopic classification of Gaia17dht/SN2017izz and Gaia17diu/SN2017jdb (in host galaxies SDSS J145121.24+283521.6 and LEDA 2753585 respectively). The candidates were discovered by the Gaia Alerts project.

The observation(s) was(were) performed with the 2.56 m Nordic Optical Telescope equipped with ALFOSC (range 350-950 nm; resolution 1.6 nm FWHM).

 
Survey Name  | IAU Name   | Discovery (UT) | Discovery mag | Observation (UT) | Redshift | Type | Phase   | Notes  
Gaia17diu    | SN2017jdb  | 2017-12-21     | 18.2          | 2017-12-28       | 0.05     | Ia   | +2w     |   
Gaia17dht    | SN2017izz  | 2017-12-16     | 18.1          | 2017-12-28       | 0.03     | Ibc  | +1w     |   

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.
