A new compilation of UBV data for stars near the Cepheid S Vul incorporates
BV observations from APASS and NOMAD to augment UBV observations published
previously. A reddening analysis yields mean colour excesses and distance
moduli for two main groups of stars in the field: the sparse cluster Turner 1
and an anonymous background group of BA stars. The former appears to be
1.07+-0.12 kpc distant and reddened by E(B-V)=0.45+-0.05, with an age of 10^9
yrs. The previously overlooked latter group is 3.48+-0.19 kpc distant and
reddened by E(B-V)=0.78+-0.02, with an age of 1.3x10^7 yrs. Parameters inferred
for S Vul under the assumption that it belongs to the distant group, as also
argued by 2MASS data, are all consistent with similar results for other cluster
Cepheids and Cepheid-like supergiants.Comment: Accepted for publication (Odessa Astronomical Publications
