When to look for the Leonid meteors in November
NASA expects the best viewing before dawn around November 17–18.
NASA's November sky guide identifies the hours before dawn around November 17–18 as a good time to look for the Leonid meteor shower. Once the Moon has set, a dark location could offer views of up to about 15 meteors an hour under ideal conditions.
Meteor showers happen as Earth passes through material left behind by a comet or asteroid. Small pieces burn brightly as they enter the atmosphere, leaving the brief streaks that observers see from the ground.
The forecast gives an approximate rate for a dark sky. Clouds, urban lighting and the observer's view of the sky can reduce the number visible.
