The largest supermoon since 1948 will be making an appearance Monday night, Nov. 14, and the Leonid Meteor shower is due to reach its peak during the early hours of Thursday, Nov. 17. The meteor show will be dulled a bit due to it coming just three days after this rare and large supermoon - so the sky will be bright with a 90% lit moon - but sky-watchers can expect to find approximately 15 meteors per hour under dark sky conditions. The November supermoon is the second of three to close out the year, but this one will see the moon make its closest pass to Earth in decades.
