The Nordic Optical Telescope (NOT) Unbiased Transient Survey (NUTS; ATel
#8992) reports the spectroscopic 
classification of two transients. The candidates were discovered by the
ATLAS survey (Tonry et al., ATel #9685). 

The observations were performed with the 2.56 m Nordic Optical Telescope

equipped with ALFOSC (range 350-950 nm; resolution 1.6 nm FWHM).

(1) Redshift from absorption lines. 

(2) Probably cataclysmic variable or dwarf nova, given the blue continuum
and the hydrogen lines in absorption observed in the spectrum. 

Classifications were performed using the GELATO (Harutyunyan et al. 2008,
A&A, 488, 383) and SNID (Blondin and Tonry 2007, ApJ, 666, 1024) tools.
