Arcturus Follows the Bear (all night)

The evening eastern sky on May evenings is dominated by the bright orange
star Arcturus, aka Alpha Bostis. This star, located 37 light-years from
Earth, is a K0-class red-orange giant with 1.5 times the mass of our sun,
and about 100 times the output of the sun in visible wavelengths. Arcturus
is visible from everywhere on Earth except for extreme southern latitudes.
For observers in mid-northern latitudes, only Sirius shines brighter.
Arcturus' name derives from the expression OGuardian of the BearO because it trails Ursa Major, the Big Bear.
