It's time for his magical journey from the North Pole with Rudolph leading the way.
[WATCH LIVE: SANTA TRACKER ]
St. Nick has his sleigh packed and will be ready to rock your chimney tonight.
Once again, you're able to track Santa's flight. As they do every year, NORAD, the North American Aerospace Defense Command, is tracking Santa in real time this Christmas Eve at NORADSanta.org.
It all starts with the NORAD Radar System called the North Warning System.
This powerful radar system has 47 installations strung across Canada's north and Alaska.
NORAD makes a point of checking the radar closely for indications of Santa Claus leaving the North Pole every holiday season.
The moment their radar says Santa has lifted off, they begin to use the same satellites used in providing air warning of possible missile launches aimed at North America.
There are even three images for children to get a better view.
You can even download NORAD's app to track Santa while you're on the go.
