Perseid meteors streak past stars—shown as arcing streaks in a long-exposure photo—as a over a Bedouin tent near Amman, Jordan, in 2004.
For anyone up to the challenge of capturing the fleeting lunar Perseid impacts this weekend, NASA's Suggs recommends at least an 8-inch (20-centimeter) telescope equipped with a digital video camera and recorder.
On average, amateur astronomers with such equipment can record one or two flashes, only a thirtieth of a second each—too brief for unaided vision.
But if you miss out this time, your next best opportunity to see lunar flashes will be during the annual Geminid meteor shower in mid-December, said Suggs, manager of NASA's Lunar Impact Monitoring Program at Marshall Spaceflight Center in Huntsville, Alabama.
