The NORAD Santa tracker is now here for 2019 so now we can all track the journey of Santa Claus through the sky.

The North American Aerospace Defense Command — better known as NORAD — launched its annual "Santa Tracker" early Tuesday morning, just after 4 a.m. ET.

Want to follow Santa’s journey? The Canadian #NORAD team will be closely tracking his route and
escorting the jolly guy as he completes his magical journey through Canadian airspace.

The organization, which exists to protect Canada and The U.S. from aerial attacks, has been tracking Santa's sleigh as it travels across the globe every Christmas Eve since 1955, back when it was still known as CONAD.

As of 12:30 p.m. ET on Christmas Eve, Santa and his nine reindeer had last been seen in Russia (how ironic) and had delivered some 2.1 billion gifts to children.

There are two "efficient" trackers for Santa Claus' trip tonight. #NORAD

"In addition to our day-to-day mission of defending North America, we are proud to carry on the tradition of tracking Santa as he travels along his yuletide flight path," said NORAD commander Gen. Terrence O'Shaughnessy in a press release late last month.

"The same radars, satellites and interceptors employed on December 24 are used year-round to defend Canadian and American airspace from threats."

A study was released in 1998 saying that Christmas Eve would be the best time for any foreign power to launch a missile attack on the United States or Canada due to NORAD's preoccupation with the Santa Tracker.

The agency is said to use infrared sensors to follow the glow of Rudolph's nose in order to pinpoint Santa's location.

Kids can track Santa's journey today by calling 1-877-HI-NORAD or visiting NORAD's official Santa Tracker website.

While NORAD maintains that its primary mission is "aerospace and maritime warning and aerospace control of North America as well as monitoring aerospace activity globally," the agency embraces its "supplementary mission" of tracking Santa every year.

"NORAD Tracks Santa is truly a global experience, delighting generations of families everywhere," reads this year's press release.

"This is due, in large part, to the efforts and services of numerous program contributors and volunteers."
