Catch the Total Lunar Eclipse on April 4th


This April 4th, 2015, most of North America, South America, Asia, and parts of Australia will be able to view a Total Lunar Eclipse.  The moon will be eclipsed in totality for about 5 minutes.  The entire event will take place, from beginning to end, for 3 hours and 29 minutes.

This will be the third eclipse in the 2014-2015 tetrad and it will be the shortest total lunar eclipse of the 21st century.

In North American time zones, the best time to catch this eclipse is before sunrise on April 4–the morning of April 4th, not the evening.  For the world’s Eastern Hemisphere–East Asia, Indonesia, New Zealand, and Australia–the greatest eclipse takes place after sunset on April 4.


You have to be on the night side of Earth while the lunar eclipse is taking place to witness this natural phenomenon.  People around the world always want to know whether the eclipse is visible from their home and at what time.  To find out the local time of the greatest eclipse in your sky, click on this eclipse calculator and put in the name of a city near you.  No time conversion is necessary because the eclipse times are given in local time.



The moon travels eastward through the Earth’s penumbra (light outside shadow) and umbra (dark inner shadow) shadow.

The yellow line depicts the ecliptic–Earth’s orbital plane.

Although the moon, in part, spends about 3.5 hours within the umbra, it is only in totality in the umbra (dark shadow) for a short while, or less than 5 minutes.

Depending on the algorithm you use, the April 4 lunar eclipse can be regarded as a very shallow total lunar eclipse or a very deep partial lunar eclipse.  Experts agree that the April 4 eclipse is a total eclipse but only of a very short duration, qualifying it for a Blood Moon.

But what causes a lunar eclipse?


Here are the North American eclipse times:
