For the 63rd year in a row the north American aerospace defence command is keeping an eye on Santa and his sleigh.
NORAD's regular mission is to watch out for Canada and the US in case someone attacks from the air.
But each Christmas since 1955 the organization has kept watch over the big guy in red and his reindeer.
People can log onto NORADSanta.org starting at 2:01 eastern time Sunday morning to watch the team get ready.
After 6 a.m eastern time you can call 1-877-Hi-NORAD or email [email protected] to get locations.
