The Nordic Optical Telescope (NOT) Unbiased Transient Survey (NUTS; ATel #8992) reports the spectroscopic classification of the supernovae SN 2016ijk/Gaia16car in the host galaxy 2MASX J01290449+4021466 and SN 2016iuc/Gaia16cay in the host galaxy NGC 5032. The candidates were discovered by the Gaia Photometric Science Alerts.

The observations 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  
Gaia16car      | SN 2016ijk | 2016-12-05.94   | 18.68         | 2016-12-09.11    | 0.053    | Ia   |  >+10 d | (1)  
Gaia16cay      | SN 2016iuc | 2016-12-07.77   | 16.7          | 2016-12-09.28    | 0.021    | Ia   | ~+5 d   | (2)  

(1) Good matches to the transient are provided by normal type Ia SNe a few weeks after maximum light.

(2) Good matches to the transient are provided by normal type Ia SNe several days after maximum light. The redshift is from the host galaxy.
