Scientific paper

High-resolution spectra of the new FU Orionis object BBW 76 are presented. Although the photometric outburst of this FU Orionis object could not be observed, its spectral characteristics clearly identify it as belonging to this class. BBW 76 shows Balmer line profiles typical for FU Orionis stars. Its absorption line spectrum and, in particular, the line widths are strikingly similar to that of FU Ori. Other similarities to FU Ori are the presence of an arclike nebula, and the FIR luminosities and color temperatures.
