True north isn't quite where it used to be.
The magnetic north pole has been moving so fast that scientists today released an update of where true north really was, nearly a year ahead of schedule.
Earth's north magnetic pole is wandering about 55km a year.
It crossed the international date line at the end of 2017. It's leaving the Canadian Arctic on its way to Siberia.
The shifting magnetic pole is a problem for compasses.
