The Diamond Ring Effect

A fitting name for a beautiful phenomenon, the Diamond Ring Effect is a spectacular sight unique to total solar eclipses.

This feature is a result of the Moon’s topography which has considerable relief — its surface is a rugged terrain of mountains, craters, valleys and such. Just before Sun disappears or just after it emerges from behind the Moon, the Moon’s rough edge, or its lunar limb, allows scintillating “beads” of bright sunlight to shine through.

These beads are also called Baily’s beads, in honour of British astronomer Francis Baily who first noted them in 1836.
