EarthSky reports

November’s wonderful Leonid meteor shower happens every year around November 17 or 18, as our world crosses the orbital path of Comet Tempel-Tuttle. Like many comets, Tempel-Tuttle litters its orbit with bits of debris. It’s when this cometary debris enters Earth’s atmosphere and vaporizes that we see the Leonid meteor shower. In 2018, the peak mornings of the shower are expected from midnight to dawn on Saturday, November 17 and Sunday, November 18. Although a bright waxing gibbous moon will be out for some of the night on the peak dates, try watching this shower during the predawn hours, or after the moon has set.
