Broken arc of illuminated lunar mountain peaks generally occuring within 24 hours of New Moon. The phenomenon is rarely observed due to the Moon's varying libration and proximity to the Sun. Note the striking resemblance to the moments before and after a total solar eclipse.
A small number of these illuminations are more commonly seen developing at the tips of fully-formed crescents.
