The Baily's Beads effect, also known as the diamond ring effect, could be seen as the moon made its final move over the sun during the total solar eclipse on Monday, August 21, 2017 above Nashville, Tennessee. The moon’s limb is not perfectly smooth because of the mountain ranges and canyons that pepper the moon’s circumference as viewed from Earth. Shortly before the moon fully blocks the disk of the sun during a total solar eclipse, flashes of light can often be seen around the circumference of the moon’s blackened disk. These are caused by sunlight passing through the canyons around the limb of the moon.
