Santa Claus is delivering Christmas presents around the world after receiving clearance for international travel during the pandemic.
This year he is classed as an essential worker and is exempt from Covid-19 quarantine restrictions.
Following his progress in the skies is the North American Aerospace Defense Command, which has activated its official Santa Tracker for this Christmas Eve.

Irish researchers investigating how Santa delivers billions of presents in the space of one night are advising children to go to bed early, to avoid catching a glimpse of him and jeopardising his operation.
Michael Fitzgerald, air traffic controller based in Shannon, said conditions are perfect for a safe journey to Ireland.
“The good news is that the weather forecast for tonight is good, clear skies, dry,” he said.
“The controllers, as they do every year, will make sure that Santa’s arrival is well looked after, we’ll make sure that the air space is clear, all the airplanes are out of the way and he can continue on his path for the night.”
