Bailey's beads are exposed during this phenomenon and are best observed along the edge of the (*) umbra.
The Allais effect occurs when pendulums undergo anomalous precession during these events, which are mapped by Besselian elements. One of these events in 1919 allowed Arthur Eddington to measure the deflection of light rays due to gravitational lensing, thus confirming general relativity. Bailey's beads are exposed during this phenomenon and are best observed along the edge of the (*) umbra. Shadow bands are seen before and after these events, which expose the corona, but can only occur during a new moon. For ten points, identify this phenomenon in which the moon blocks out the Sun.
