A brief overview of what to see in the sky with the unaided eye during April evenings:
Stars and Constellations
● Some prominent constellations visible in the evening sky are Bootes, Coma Berenices and Virgo
● Follow the ‘handle’ stars of the Big Dipper star group southward to the star Arcturus in Bootes, and then further south to the star Spica in Virgo
● Arcturus is a bright (first magnitude) orange star rising in the east during spring evenings
● Spica is a bright (first magnitude) blue star lower in the southeastern sky during spring evenings
● Coma Berenices is a small group of faint stars west of Arcturus, and nearly overhead by late evening
● The region of sky in the direction of Virgo and Coma Berenices contains numerous galaxies that can be seen in a moderate-size telescope in a dark sky
