June Constellations
The transition to summer constellations continues during the month of June.
In the southern sky, Gemini can be found along the western horizon after sunset, with Cancer, Leo, Virgo, Libra, Scorpius, Serpens/Ophiuchus, and Aquila in a loose lineup across the evening sky. Hydra stretches across much of the horizon as well, while higher up, we can see Ursa Major, Boötes, Hercules, and Cygnus.

Meanwhile, facing north, Auriga, Camelopardalis (“The Camel”), Cassiopeia, Cepheus, and Cygnus are visible along low in the evening sky, with Ursa Major (“The Big Dipper”), Ursa Minor (“The Little Dipper”) and Draco circling the north celestial pole.
By the end of the month, Gemini will have mostly set in the west as evening arrives, while Sagittarius will be rising in the east.
