Watchers in the United States have been waiting for this date for years. On August 21, 2017, there's going to be a total eclipse of the sun. With the path of totality stretching from Oregon to South Carolina, people can see the eclipse from coast to coast. The timing of the eclipse will provide the opportunity for viewers to see one of the biggest astronomical events of the century, just a few weeks after enjoying one of the biggest meteor showers of the year. Every August, Earth passes through a stream of debris from comets with tuddle, source of the annual per seed meteor shower. This year, the shower will peak on the nights of August 11, 12 and 13. Although the comet is far away, currently located beyond the orbit of Uranus, a trail of debris from the comet stretches all the way around its orbit, back to where it nears Earth's orbit. As our planet crosses the debris zone, the upper atmosphere will be pelted by specks of comet dust traveling 132,000 miles per hour. At that speed, even a flimsy speck of dust makes a vivid streak of light when it disintegrates, a meteor. When the swiff tuddles meteors streak out of the constellation per sees, they are called per seeds. Astronomer Bill Cook of NASA's Meteor Roar and Environment Office offers these observing tips. If it's not cloudy, get away from the bright lights, lay on your back and look up. Remember to let your eyes get adjusted to the dark. It takes about 30 minutes. You'll see more meteors that way. If you don't need to look in any particular direction, meteors can generally be seen all over the sky. Not all the meteors you'll see belong to the per seed meteor shower. Some are sporadic background meteors. Others are weaker showers, also active in August, including the alpha-capacornids, the southern delta-aquirids, and the capacignids. But the vast majority will be per seeds. Cook says if you see a meteor, try to trace it backwards. If you end up in the constellation per sees, there's a good chance you've seen a per seed. Under ideally dark skies, observers can often see dozens or even more than a hundred per seeds per hour when the shower peaks. This year, the glaring light of a bright, waning, gippos moon will interfere, reducing the number of visible meteors. Now for the good news, that same moon is heading toward the sun, narrowing as it goes until the thinning crescent disappears into a black disc that will perfectly cover the sun on August 21st. A meteor shower, followed by a total solar eclipse, August doesn't get much better than that.
