We present the results of a spectroscopic analysis and spectral energydistribution (SED) modelling of the optical counterpart of the infrared sourceIRAS 22150+6109. The source was suggested to be as a Herbig Be star located inthe star forming region L 1188. Absorption lines in the optical spectrumindicate a spectral type B3, while weak Balmer emission lines reflect thepresence of a circumstellar gaseous disc. The star shows no excess radiation inthe near-infrared spectral region and a strong excess in the far-infrared thatwe interpret as radiation from a large disc, whose inner edge is located veryfar from the star (550 au) and does not attenuate its radiation. We concludethat IRAS 22150+6109 is an intermediate-mass star that is currently undergoinga short pre-main-sequence evolutionary stage.
