Mariusz Gromadzki report/s a classification of object: AT 2022bhu
Type: Varstar
Remarks: Spectrum shows stellar continuum affected by Galactic and Interstellar extinction with absorption lines of hydrogen (Balmer series), He I and few diffuse interstellar bands. Halpha shows narrow emission inside absorption profile. This suggests that the transient is a brightening of an early Be-type stars.
