Moonset and Sunrise in Rio

Penumbral Lunar Eclipse at TED Global 2014

Thanks to Bruno at TED pointing out the phenomenon, I rose early to see the moonset and sunrise. These photographs unfortunately don’t capture the actual simultaneous view of the moon setting exactly as the sun was rising due to my location, which is the penumbral phenomenon.

A penumbral lunar eclipse takes place when the Moon moves through the faint, outer part of the Earth’s shadow. This type of eclipse is often mistaken for a normal full Moon.

A penumbral lunar eclipse occurs when the Sun, Earth and Moon align in an almost straight line. When this happens, the Earth blocks some of the Sun’s light from directly reaching the Moon’s surface, and covers a small part of the Moon with the outer part of its shadow, also known as the penumbra. The rest recieves direct sunlight and can be as bright as a full Moon.

With thanks to
