June Sky: Reckoning by Starlight
You'll never lose your way in the
summer sky – even out in the boondocks – with these three stars to
guide you.

One of the most shocking things
about a dark country sky is how disorienting it is: The brain has a
difficult time finding recognizable patterns in the multitude of stars. Urban
skies are much easier to read, reduced to their brightest, most distinctive
elements. Fifteen minutes is all you need to learn your way around the city
stars of summer.
The key is a grouping of three stars
now rising in the eastern sky, opposite the setting sun. The highest and
brightest is Vega. To the left is Deneb, surrounded by dimmer stars that form a
large, loose cross. To the right is Altair, tightly flanked by two fainter
stars. Collectively, the three form a pattern called the Summer Triangle.
Each night through the summer months
they rise a little earlier and appear to reach higher. When the Triangle is
well above the horizon (around 11 p.m. this month), its long end, with Altair
at the tip, faces almost due south, making it easy to get your bearings.
Look farther south and a bit left,
and you’ll see ruddy Antares, which roughly marks the direction toward the
center of our galaxy. Turn left and you are facing east, where beautiful,
orangish Arcturus is high but sinking as the Triangle rises. Turn left again,
and you are pointed north, with the Big Dipper balancing vertically on its
bowl. Now you are fully oriented — no GPS required.
One comment: June 2013 is a good
time to get your local bearings, like North, South, East, and West from where
you live down pat in your mind.
