While you’re waiting for the Perseids to appear — or on any other clear August evening — you won’t fail to notice a very bright beacon hanging over the western horizon. That’s Venus, and it sets about 1½ hours after the Sun all month. Much dimmer Saturn is positioned to Venus’s left by about four times the width of your fist held at arm’s length.
August is also a great month to seek out the Teapot asterism in Sagittarius. It's a group of eight medium-bright stars whose handle is on the left and whose spout, tipped down a bit, is on the right. From northern states and Europe, the Teapot is low in the south, so make sure you have a clear, unobstructed view in that direction.
