Sure, he sees you when you're sleeping. But now it's your turn to keep tabs on the Man in Red.
This season you can track Santa's flight in Google Earth, receive mobile phone updates on his whereabouts, and check in regularly for high speed-photo and video footage of his reindeer and sleigh as they deliver presents around the world. He's also on Facebook and Twitter.
The Colorado-based North American Aerospace Defense Command (NORAD) is charged with keeping the United States and Canada safe from dangers originating from the sky or space.
So it stands to reason they would use radar, satellites, Santa Cams and fighter jets to track Santa's flight path from the North Pole, across North America.
According to their website: "Satellites positioned in geo-synchronous orbit at 22,300 miles from the Earth's surface are equipped with infrared sensors, which enable them to detect heat. Amazingly, Rudolph's bright red nose gives off an infrared signature, which allows our satellites to detect Rudolph and Santa."
In addition, they use pre-positioned high-tech cameras to capture images of Saint Nick. And of course, fighter pilots equipped in F-16's are on hand to welcome the Big Man to the United States.
The website also includes a countdown and activity page that's sure to entertain. Don't stay up too late though. He still knows when you're awake.
