The distribution of young open clusters in the Galactic plane suggests the existence of the outer ring R1R′2 in the Galaxy. The solar position angle θb providing the best agreement between the observed and model distribution is θb = 35±10°. We compared the θb values derived from three different catalogues of open clusters and they appear to be consistent within the errors.
