The ‘ring of fire’ solar eclipse occurs when the Moon is at its furthest from Earth. This means it is too far away to completely cover the Sun, leaving a ring of light
A rare type of solar eclipse that creates a ‘ring of fire’ around a blacked out Sun will cast a dramatic shadow over Russia and Canada later this week.
Skygazers in the UK and US won’t miss out entirely though, as a partial solar eclipse will be visible, with about 30 per cent of the Sun blocked out in Scotland, 20 per cent in southern England and as much as 70 per cent over Eastern US states.
This is known as an annular eclipse, occurring when the Sun and Moon are exactly in line with the Earth, but the apparent size of the Moon is smaller than that of the Sun.
It results in the Sun appearing as a very bright ring, or annulus, surrounding the Moon, a phenomenon dubbed ‘the ring of fire by astronomers.
British and Irish observers will see a crescent Sun instead of a ring, and in the US, viewers will be able to see a partial eclipse at sunrise, another rare phenomenon.
In the UK the partial eclipse will begin at 10:08 BST on June 10, reaching maximum coverage – or about a third – at 11:13 BST, ending at 12:22 BST the same day.
‘From the UK, the annular solar eclipse will be a partial eclipse, meaning that we’ll only see the Moon pass in front of a small part of the Sun,’ said Dr Emily Drabek-Maunder, an astronomer at the Royal Observatory Greenwich.
She warned that looking directly at the Sun, even one partially eclipsed, can cause serious and permanent damage to the eyes.
‘Never look at the Sun directly or use standard sunglasses, it can cause serious harm to your eyes,’ added Dr Drabek-Maunder.
It also isn’t safe to look at the Sun through binoculars, telescopes or a camera lens without specialist filters – so best to avoid taking direct images.
Using a simple pinhole projector, solar eclipse viewing glasses, which can be purchased online, or special solar filters –are viable alternatives.
‘You can make a projector by poking a small hole into a piece of card,’ said Dr Drabek-Maunder, adding you hold the card to the Sun so it shines through the hole on to a piece of paper placed behind the card.
‘You will be able to see the shape of the Sun projected on to the piece of paper and watch its shape change as the Moon passes in front of the Sun.’
The Royal Observatory Greenwich is also live-streaming the eclipse on its website and YouTube channel.
The ring of fire is best viewed from Qaanaaq, a town in Northwest Greenland, but should be visible across much of Canada and Russia.
People in the Northeastern US will get to view a rarer sight than the ring of fire – a partially eclipsed sun at sunrise.
This unusual and rare sunrise eclipse will be visible up the Atlantic coast, according to astronomers.
From South Carolina and moving north, skygazers should look north just after sunrise to spot the Moon taking a bite out of our star as it slowly rises over the horizon.
Philadelphia, New York and Boston will see 70 per cent of our star eclipsed by the Moon during sunrise.
A small stretch of coast in the US, in New Jersey and New York, will see ‘red devil horns,’ also known as the crescent sun.
UK stargazers will see the sun with a ‘bite taken out of it’ as the highest level of eclipse will be 32 per cent in northern Scotland, going as low as 20 per cent in southern England.
Current forecasts suggest clear skies over much of the UK on June 10 at about 10:10 BST, the point where the Moon will appear to pass in front of the sun.
The next partial eclipse after this, visible from the UK, will be on March 29, 2025 when 60 per cent of the sun will appear to be covered by the Moon.
This will be followed by another on August 12, 2026 where the UK will see up to 90 per cent of the sun obscured. The UK won’t see totality until July 23, 2093.
