Image of "Bailey's Beads" just prior to 2nd Contact (start of totality) during the August 21, 2017 total solar eclipse. MTO viewed the eclipse 3.7 miles southwest of Dorchester, Nebraska and experienced 2m 33s of totality. Bailey's Beads are caused when the last sliver of sunlight is broken up by the mountains and valleys along the outer edge of the lunar disc.
The insert at right is the Kaguya/LRO limb profile chart showing the predicted orientations of mountains and valleys around the moon's edge, and taking into account its librations, at the time of eclipse as viewed from a specified location on the earth's surface. It also models the expected location of Bailey's Beads just prior to 2nd contact. The chart is from an interactive Google map of the central path of the eclipse prepared by Xavier M. Jubier.
Image taken with a Canon DSLR camera through an unfiltered Astro-Physics 5" F/8 Starfire refractor (1/250 sec. ISO 100).
