Gaia G_BP, G_RP color-magnitude diagram of the stars within a 1′ angular distance from Wray 15−0751. The 18 cluster stars selected on the basis of their UBV colors in Pasquali et al. (2006) are marked with back circles, as is Wray 15−0751 which is the bright star at the top right of the diagram. Gaia DR3 observations covered the period 2014−2017, during the late S Dor phase of Wray 15−0751, as noted in Section 3, and its magnitude was declining toward quiescence, while its color was becoming gradually bluer.
