The Not So Extraordinary Globular Cluster M31 037 - B327
  A velocity dispersion has been measured for the luminous globular cluster M31 037 - B327, claimed to be the most massive star cluster in the Local Group and to be a young ``super star cluster'' that has survived to an old age. M31 037 - B327 has a mass comparable to that of M31 G1, but not significantly larger. Although near the upper end for the mass distribution of globular clusters, it is not an unprecedented extraordinary object.
