Baily’s Beads

As the moon approaches total coverage of the sun, the last rays of light shine exhibit a “beading” effect:

As the Moon covers the Sun during a solar eclipse, the rugged topography of the lunar limb allows beads of sunlight to shine through in some places while not in others. They are named for Francis Baily, who explained the effects in 1836.
