1 GCVS Team Identical to VES 28, as it follows from latter star's coordinates and magnitudes in [G.V.Coyne, S.J., T.A.Lee, E.de Graeve, S.J., Spec Vat 1, 181, 1974.], but the star is actually invisible in the chart in [G.V.Coyne, S.J., T.A.Lee, E.de Graeve, S.J., Spec Vat 1, 181, 1974.], where a faint companion, to 0.4'N of the variable, is erroneously marked. Similarly, it is identical to +29deg 104, judging from the latter star's photometry and spectral type from [B.Westerlund, ApJ Suppl 4, N37, 1959.]; however, the star is plotted slightly offset (by 0.8' to E) in the chart in [B.Westerlund, ApJ Suppl 4, N37, 1959.].
