Crescent Moon and Three Planets

On the 20th, Mercury will be positioned just over 1-degree directly above Saturn, both planets positioned below and to Venus’ left. A narrowing crescent Moon will slide past Venus on the mornings of the 21st and 22nd. That same sliver of Moon—less than 36 hours from new phase—will be passing well above and to the left of Saturn on the morning of the 22nd. By then, Mercury will have brightened to magnitude –1.4, matching Sirius (the brightest star in the sky).
