This weekend on September 27 there will be a total lunar eclipse. And not only that–it’s a supermoon! That means it’s a total eclipse that happens when the moon is closest to Earth in its orbit. This is a rare event. It hasn’t happened in over 30 years, so you definitely don’t want to miss it.

The total eclipse will last one hour and 12 minutes, and will be visible to North and South America, Europe, Africa, and parts of West Asia and the eastern Pacific. Earth’s shadow will begin to dim the supermoon slightly beginning at 8:11 p.m. EDT. A noticeable shadow will begin to fall on the moon at 9:07 p.m. EDT, and the total eclipse will start at 10:11 p.m EDT.

Be sure to look up!

Wait, what’s a lunar eclipse again?
And how is it different from a solar eclipse?
