It was observed from the 1.88 m Telescope of Kottamia Observatory in Egypt. The main photometric parameters have been estimated and compared with the results that determined for the cluster using JHKs 2MASS photometric database. NGC 6631’s diameter is estimated to be 10 arcmin; the reddening E(B-V)= 0.68 ± 0.10 mag, E(J-H)= 0.21 ± 0.10 mag, the true modulus (m-M) o = 12.16 ± 0.10 mag, which corresponds to a distance of 2700 ±125 pc and age of 500 ± 50 Myr. The complete analysis for Mayer3 will also be presented. |
