Everyone knows that Santa Claus and his magic reindeer deliver presents to houses all over the world on Christmas Eve. Exactly how he does it is still a mystery, but you can track his progress on an interactive 3-D map.

The North American Aerospace Defense Command has been tracking Santa on his yearly voyage since the 1950s, and now has a live display showing where he is and where he’s heading.

Santa was seen over Ukraine around 2:45 p.m. on Christmas Eve.
