Astro Bob's Backyard Astronomy: See the Perseids Tonight
Bob King tells us tonight could be a great night to see the Perseids, an annual meteor shower that occurs when the earth passes through the debris left by the Comet Swift–Tuttle.
You'll see them best once it gets truly dark, starting around 10 pm. Look to the northeast sky, in the constellation Perseus (whence the name Perseids), just below the "W" of the constellation Cassiopeia. The meteor streaks that you will see radiate from that point in the sky.
But after about 12:30 am the rising moon (in a half-moon phase) will rise and begin to cast more light, making it harder to see them.
