    Intro and Visual description

    Between Cygnus and Sagittarius, with Altair (its brightest star) making the south end of the Summer Triangle (along with Deneb of Cygnus and Vega of Lyra). As the night sky changes, Aquila the Eagle and Cygnus the Swan swing slowly westward across the sky towards the horizon. The Eagle sets tail first, followed closely by the Swan, who dives beak first below the western horizon.

    Intro and Visual description

    Skywatchers have long-repeated the catch-phrase "Arc to Arcturus" (Arc-TUR-us). Follow the curve of the Big Dipper’s handle to the fourth brightest star in the sky. Arcturus belongs to the ancient constellation Bootes (BOW-oh-tees). Look for a pentagon above Arcturus forming the torso of the herdsman.

    Some prefer to see Bootes as a one-scoop ice cream cone. Just to one side lies Corona Borealis, the Northern Crown. With bright Gemma ("Jemma") in its center, like a second scoop of ice cream that melted in the heat of summer and fell off the top.

    Intro and Visual description

    A semicircle of stars between Bootes and Hercules, featuring the bright star Gemma (jewel). To locate the Northern Crown, find Arcturus and Vega, the two brightest stars in the northern hemisphere. Draw a straight line between them and you will find not only the mighty Hercules, but the splendid Corona Borealis.

  • Lyr - Lyra the Harp

    IAU Constellation

    Intro and Visual description

    To find Lyra, look for Vega, which forms the brightest point of the Summer Triangle. The summer triangle consists of Deneb in Cygnus the Swan, Altair in Aquila the Eagle, and bluish Vega in Lyra the Harp. Vega soars almost directly overhead in summer, while the bright stars of winter nights are hidden almost directly beneath our feet. Look for a small parallelogram of stars near Vega which forms the frame of the harp.
