The Night Sky
Friday, June 21
· As Mercury fades and descends below Venus day by
day, how long can you keep it in view?
· After dark, look for fire-colored Antares to the lower
right of the bright Moon.
Saturday, June 22
· The largest full Moon of 2013 rises around sunset and
shines all night. Tomorrow night it's almost as full and
almost as large (for the longitudes of the Americas, since
the Moon is exactly full at 7:32 a.m. Sunday morning
EDT.) On both nights, though, this "supermoon" is only a
trace larger than an average Moon: 7% wider. Read
about the supermoon on our blog.
Sunday, June 23
· This is the time of year when the two brightest stars of summer, Arcturus and Vega, are about equally high
overhead shortly after dark. Arcturus is toward the southwest, Vega toward the east.
Arcturus and Vega are 37 and 25 light-years away, respectively, and represent the two commonest types of
naked-eye stars: a yellow-orange Kgiant and a white A main-sequence star. They're 150 and 50 times brighter
than the Sun — which, combined with their nearness, is why they dominate the evening sky.
Monday, June 24
· Look a third of the way from Arcturus to Vega for dim Corona Borealis, the semicircular Northern Crown. It has
one moderately bright star, Alphecca (magnitude 2.2). Look two thirds of the way for the dim Keystone of
Hercules, whose brightest star is magnitude 2.8.
