The Nordic Optical Telescope (NOT) Unbiased Transient Survey (NUTS; ATel #8992) reports the spectroscopic classification of AT 2018bbz in host galaxy PGC 060339. The candidate was discovered by F. Ciabattari, E. Mazzoni, S. Donati within Italian Supernovae Search Project.

The observation was 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  
AT 2018bbz   | AT 2018bbz | 2018-04-26.02   | 17.9          | 2018-04-28.99    | 0.028   | Ia    | +2w   |  (1) 

(1) redshif from the host SDSS spectrum, SNID result is z=0.036+/-0.003.

Classification was performed using SNID (Blondin and Tonry 2007, ApJ, 666, 1024) tools. Calibrated spectra and additional information can be retrieved in the IAU Transient Name Server.
