The best viewing conditions for the eclipse are from North and Central America, parts of northern Europe and East Asia.
Total eclipses can turn the Moon a shade of pink or dark red the eclipse began early on Tuesday morning GMT.
It is the first total lunar eclipse in three years and the first to fall on the Winter Solstice - the shortest day of the year - in nearly 400 years.
