For most of the UK the eclipse will be partial as the Earth's shadow will not cover all of the Moon. For some far western regions, and across the Americas, the eclipse will be total, weather permitting. As the Moon moves into the Earth's shadow, it will gradually darken before turning a dusky red, resulting in a stunning "blood moon".

Most of the U.S. should be able to see the total lunar eclipse tonight, but clouds will be problematic for many.
