A Partial Lunar Eclipse

What's happened to the Moon?

This past weekend, once again, part of the Moon moved through the Earth's shadow.

This happens about once or twice a year,
on the average, but not each month since the
Moon's orbit around the Earth is slightly tilted.

Pictured above, the
face of a full moon is partly blocked by Earth's clouds, and partly darkened on the upper right by
Earth's umbral shadow.

Clouds permitting, the partial lunar eclipse was
visible from the half of the Earth facing the Moon at the time of
the eclipse, which included much of Earth's
Pacific Rim.

On July 11, a total eclipse of the Sun will be visible in a
thin swath of Earth crossing the southern
Pacific Ocean.
