Experts say up to a quarter of the sun will be hidden at the height of the eclipse, making the sun “appear to have a bite taken out of it”.
Those in Northern Ireland and northern Scotland are expected to enjoy the best views.
Jake Foster, astronomer at Royal Observatory Greenwich, said: “Those viewing from the UK will see between 10% and 20% of the Sun covered by the Moon.”
As a result, experts say it won’t fall dark as it does during a total solar eclipse when the Moon completely blocks the sun’s light.
Jake added: “Even though a portion of the Sun’s light will be blocked, it will not get noticeably darker in the UK during the eclipse.”
Tuesday’s event will start just after 10:00 when the Moon will begin to pass between the Sun and the Earth.
It will peak nearly an hour later, between 10:50 and 11:00, and end about 11:45 - although times will vary slightly depending on where in the UK you are.
REMEMBER!
It’s important never to look directly at the sun as it can permanently damage your eyes.
