Zusammenfassung:The star LSS 3027, embedded in a parabolic-shaped dark nebula, and several stars in its vicinity, were observed photometrically and spectroscopically to investigate whether they are candidates of very young Herbig Ae/Be stars. Only the star LSS 3027B is without doubt a very good candidate. Its H-alpha emission is very strong, indicating an extended atmosphere around the star, and its near- and far-infrared spectral energy distributions exhibit a strong excess radiation, which most probably is caused by a thick dust shell in the close environment of the star. It can be shown that it is embedded in the dark cloud mentioned above. From its properties, it is believed that the remarkable object LSS 3027B is a typical Herbig Be pre-main-sequence object.
