Map of the umbra and penumbra path of the solar eclipse of 08/21/2017

Baily's Beads

Baily's beads are the bright points of sunlight that shine through the valleys along the Moon's limb in the final seconds before and after totality. The simulations below show them at second contact (C2), the start of totality, and third contact (C3), the end. These simulations are computed for the point of maximum eclipse. Baily's beads at any other location within the eclipse path can be simulated on the interactive map.
