The moon dominates the early hours of evening in the southwestern sky.
On Sunday night the first quarter moon enters the zodiacal constellation Virgo. It takes three days for the moon to pass through this large and long constellation.
On Tuesday night the gibbous moon appears near Spica, the brightest star in the constellation and the principal star in Virgo. It has a blueish white tint. Spica is actually two stars or, in other words, a binary star. These two stars are too close together to be seen separately in a telescope. They orbit each other in four days.
