The Moon will not obscure this year's Leonid Meteor Shower. The shower will peak on 17/18 November. The ZHR this year is predicted to be 10 and it is quite low this year. The source of the Leonid meteor shower is actually debris from the comet Tempel-Tuttle. Every year, the earth passes through the debris cloud left by the comet as sand-sized specks enter the earth's atmosphere. The Leonid radiant is within the Sicke Asterism.
