The music of the spheres : $b A nature lover's astronomy
Grondal, Florence Armstrong
Astronomy
Our neighbor Capella is a beautiful star. It flashes like a great
solitaire, a star-poem of loveliness in color. Early in August, in the
far northeast, its creamy-whiteness is accentuated by seashell pinks
which splash through the thickened atmosphere like the effervescence of
a rainbow. This star, with two others,--Vega, a delicate blue and
Arcturus, an orange-gold,--are the three brightest stars nearest the
north. Since they are easy to locate and visible most of the year they
are usually the star lover's favorites among the stars. Learn to locate
these exquisite isles of starlight by using the Big Dipper as a base
from which to start.

CHAPTER VIII
GREAT STARS OF THE SOUTH
SPICA FORMALHAUT
ANTARES SIRIUS
WITH the exception of the stars in the constellation of Orion,--Spica,
Antares, Formalhaut and Sirius are the only stars of the first magnitude
south of the celestial equator which are visible from any point in the
United States. The Orion stars are winter stars and will be taken up in
the chapter to follow, but these four stars, each of which in turn looms
lonesomely in the south, are representatives of the seasons, and their
very names, Spica, Antares, Formalhaut and Sirius, bring to mind
successively, spring, summer, autumn and winter.
Spica, the "Spring Star," rises at sunset on the 10th of April and
crosses the meridian during the early evenings of April, May and June.
Its beautiful silvery-white flame first appears just a little south of
east and it takes only 5 hours and 25 minutes to cover half of its arc
across the sky. It is then a little less than half way up from the
horizon and hangs on the same curve from the Big Dipper's handle as
Arcturus.
Antares rises at sunset on the first of June and passes the meridian
early in the evening during June and July. It rises farther south of
east than Spica and takes only 4 hours and 23 minutes to reach the
meridian. It is then only one-quarter of the way up from the horizon.
Being a brilliantly red star in a conspicuous anchor-like constellation
near the Milky Way, it is very easy to locate.
Formalhaut rises at sunset about the 10th of October and reaches the
meridian about 4 hours later. It first appears in the southeast and
skims in a short arc closer to the horizon than any other first
magnitude star.
