Swathes of the Northern Hemisphere will have the chance to experience an annular or partial eclipse of the Sun today.An annular eclipse occurs 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 as the ring of fire.But - weather permitting - observers in the UK and Ireland on Thursday morning will see a crescent sun instead of a ring, as this will be a partial eclipse.The phenomenon will begin at 10.08am on June 10 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.Views of the partial solar eclipse will be somewhat fleeting across certain parts of the UK due to cloudy skies.But those in central and south-east England will have clear spells to witness the spectacle.An annular solar eclipse seen from Chiayi in southern Taiwan in June 2020.
