A close series of consecutive exposures are combined in this
intriguing composite of the Full Moon slowly crawling, across
the sky. Beginning on the upper right at 19:42 UT and ending at
22:14 UT on the sequence follows the Moon from Germany as it
passes through Earth's shadow in a partial lunar eclipse. Near
the top, the Moon just grazes the southern edge of Earth's dark
central shadow, or umbra. in the darker part of the outer shadow
region, the penumbra, is also apparent on the lunar disk. the
relative size and shape of the Earth's and the Moon are easier
to see along the segments of this lunar caterpillar. Nearly
impossible to follow with the eye though, a penumbral lunar
eclipse, the Full Moon passing only through the pale outer
penumbral shadow, begin on May 25.
