Description:
At ~2° NW of Alhena. The members of the double star are very difficult to separate because the angular separation is rather weak (20"). But while observing attentively during a few minutes, I am able to separate the secondary and the primary star, which are of the same brightness. As the stars are very close each other, that makes more difficult to find  a color for each one of them. I would say that their colour is white.
