If you caught the September 7 th, 2006 partial lunar eclipse centered over the Indian Ocean region, you caught the last member of this saros cycle. The final member of saros series (a barely perceptible penumbral eclipse) occurs on… (mark your calendars) May 7 th, 2403.

A partial lunar eclipse can be visible across the lower 48 tonight. This Full Moon is also a supermoon so the moon will also appear bigger than usual. The moon will ender Earth's shadow at 8:41 PM. The moon will be slightly dimmer around 10:13 PM and the peak will occur at 10:44 PM.

It’s not often that a partial lunar eclipse and a supermoon occur at the same time. After Tuesday night, it won’t happen again until 2033. A lunar eclipse happens when Earth passes between the sun and moon, creating a shadow that darkens the moon.

The final full moon of the summer season, the Harvest supermoon, will rise tonight during a partial lunar eclipse. Here's when to watch.

A partial lunar eclipse will coincide with this week's Harvest Moon, which also happens to be an exceptionally bright and large supermoon.

It is a big, big, big night for stargazers across the world. Later this evening, we will have the Supermoon and partial lunar eclipse.
