Moon and Sun Ring of Fire

Updated: Jul 1

Partial Solar Eclipse: How and when to see phenomenon in UK this week - and where 'ring of fire' will be visible from. The events only occur every one or two years, when the sun and moon are exactly in line with the earth.


Skygazers will be treated to a partial solar eclipse over the UK this week - as the moon passes between the earth and the sun.


Tomorrow morning, it will be possible too see nearly a third of the sun being blocked out by the moon in what is known as an annular eclipse - similar to the crescent sun (above) pictured in 2015.


These only occur every one or two years, 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. This causes the sun to appear as a very bright ring, or annulus, in a phenomenon dubbed the "ring of fire".

However, observers in the UK and Ireland will see a crescent sun instead of a ring, as this will be a partial eclipse. The ring of fire will be visible from Russia, Greenland and northern Canada.


Even though for the UK, a large part of the solar disc will be covered, experts have warned that looking at the partially eclipsed sun without appropriate protection can cause serious and permanent damage to the eyes.

Dr Emily Drabek-Maunder, an astronomer at the Royal Observatory Greenwich, said: "Never look at the sun directly or use standard sunglasses, it can cause serious harm to your eyes."

She said the phenomenon would begin at 10.08am on 10 June in the UK, with the maximum eclipse occurring at 11.13am, when the moon will cover close to one-third of the sun.


The partial eclipse will end at 12.22pm.


The Royal Observatory Greenwich will be live-streaming the eclipse on its website and YouTube channel.
