unique places
The following sequence shows some unique views such as the totality of a solar eclipse set – the shadow band, the diamond ring, the Sun’s corona, Bailey’s pearls and the Sun’s chromosphere.
shadow band There are wavy lines of alternating light and dark that can be seen on the ground and along the walls for about a minute before totality.
a Diamond Ring It is seen before and after about 10 to 15 seconds before totality. The solar corona, along with a single gem of light from the Sun, produces the diamond ring effect.
the outermost part of the Sun’s atmosphere, or corona, becomes more prominent as the diamond ring fades. The silhouette appears as a faint ring of rays surrounding the Moon.
Bailey’s Pearls Appears about five seconds before totality. They are tiny bead-like drops of light on the edge of the Moon created by sunlight passing through the gap between mountains and valleys on the Moon.
seconds after totality, Sun’s chromosphere, which is the second outermost layer of the Sun’s atmosphere, emits a reddish glow.
The events are subsequently repeated in reverse order as totality begins to come to an end.
