A wide band of north and central Spain, plus a sliver of Portugal and parts of Greenland and Iceland will experience a rare total eclipse.
The light of the setting sun will be virtually blocked out across much of western Europe, including the UK, France, Belgium, Switzerland and northern Italy.
This total eclipse will be the first in mainland Europe in two decades.
The last event of this kind visible from the UK occurred in 1999, when parts of Devon and Cornwall were in the path of totality.
The next total solar eclipse visible in the UK is not due to occur until 2090.
