Today:
As the sun sets just before 8 PM, the Waxing Crescent Moon will be due west. By 10 PM, the twilight should be dim enough for the star Regulus to be visible just below and right of The Moon. Looking back toward the west and southwest, The Moon and Regulus align well with Mars, which appears above the moon and to its left, and Spica, higher up and almost due southwest.
Sunday:
The Milky Way arches high across the eastern skies in the evening, extending down to the north, where it appears dimmer, and toward the south, glowing noticeably brighter, home to the center of our Galaxy. The Milky Way swings overhead through the course of the night.
Monday:
Low in west by 9:20 PM, you can catch the Crescent Moon and Mars in close proximity, with the red/orange Mars just the right of the Moon. As they emerge from the twilight, the two will be diving quickly toward the horizon, disappearing below it a little after 10:00 PM.
