Possible membership for the 51-day Cepheid GY Sagittae in a new OB association
New photometric and spectroscopic observations of the 51-day Cepheid GYSagittae and nearby OB stars are presented which confirm the PopulationI nature of the Cepheid and suggest its possible membership in ananonymous OB association. On the basis of agreement in spatial location,reddening, and evolutionary status, it appears that GY Sge is probably amember of a loose association consisting of at least 17 luminous starsat a common distance of 3.47 + or - 0.13 kpc. The equivalent B-starreddening of 1.29 + or - 0.06 derived for the Cepheid, together with theassumption of association membership, results in an intensity-meanabsolute magnitude of -6.34 + or -0.19.
