A classification spectrum of BD +60 73, reported to be the optical counterpart to IGR J00370+6122 (ATel #281), was taken on the night of 2003 July 7th with the 2.5-m Issac Newton telescope at La Palma. The derived spectral type is BN0.5II-III, where the composite luminosity class indicates an intermediate luminosity. The Nitrogen enhancement is moderately high, with numerous NII lines being rather stronger than corresponds to the spectral type.
