September 10th, 2015
The waning Moon now joins Mars and Venus in the pre-dawn twilight. This morning provides a good opportunity to see all three together (especially for those in the northern hemisphere) but observers all over the world can also catch Earthshine on the waning crescent Moon.
Next month it gets even better. Three planets, one Moon and one bright star come together as Jupiter joins the waning crescent Moon, Venus, Mars and Regulus in the pre-dawn twilight. Set your alarm clocks for October 10th for this not-to-be-missed early morning event! (It’s a Saturday, so no excuses!)
