Andreoli.V ; Castellani.F report/s a classification of object: AT 2023dez
Type: Other
Remarks: Low resolution spectrum (6 X 600s) was obtained on 2023-03-17.802 from Osservatorio Monte Baldo located in Novezzina (Italy) by 0.25-m telescope + Alpy600 spectrograph (with dispersion 4.9 Ang/pix). The spectrum shows H-alpha emission (6562.8 Ang), a weak absorpion of H-beta (4861.03) problably filled up by the accretion disk and strong absorpions of the other Balmer lines and He I (4471;4922;5876 Ang). It also shows interstellar NaI D1,D2 (5885,5890 Ang). These features belong to a type Be Herbig star. Furthermore the coordinates are coincident to LS I+56 76, object prensent in the Catalog of galactig OB stars (Reed 2003). We propose the identification for this transient as a Be star.
