Description
A colour magnitude diagram to V=20 is given for 395 stars in the heavily reddened open cluster NGC 6649. The absorption-corrected distance modulus is 11.00 +- 0.15 mag assuming R(OB)=3.27 +- 0.10 for NGC 6649 and based on a ZAMS with zero point referenced to a Pleiades distance modulus of 5.56 mag. The range of reddening over the 5 arcmin diameter of the cluster is ΔE(B-V)=0.3 mag. NGC 6649 contains the double mode Cepheid V367 Sct. (author)
