The Earth's shadow begins to fall on the moon during a total lunar eclipse, as seen above Miami, Oct. 8, 2014. Wilfredo Lee—AP by [Alex Rogers](https://time.com/author/alex-rogers/) ## Alex Rogers Apr 3, 2015 4:58 PM UTC The moon will line up directly inside Earth’s shadow Saturday morning, creating a [nearly 5-minute](http://science.nasa.gov/science-news/science-at-nasa/2015/30mar%5Flunareclipse/) lunar eclipse—the [shortest](http://www.nasa.gov/topics/solarsystem/features/watchtheskies/ask-an-astronomer-about-the-shortest-lunar-eclipse-of-the-century-on-april-4.html#.VRtHkvnF%5F1M) of the century. At 6:16 a.m. EDT, the moon will first enter the Earth’s shadow and will be totally eclipsed at 7:58 a.m., according to NASA. Those on the West Coast of the United States will have a better chance of seeing the eclipse than those east of the Mississippi River, who will only be able to see a partial eclipse because of the sunrise. India, western China and parts of Russia will be able to see portions of the eclipse after sunset, while Greenland, Iceland, Europe, Africa and the Middle East won’t be able to see it at all. Those that can’t walk outside to see the Blood Moon can check it out online at the Los Angeles-based Griffith Observatory’s [website](http://www.griffithobs.org/events/Lunar%5FEclipse%5FApril%5F2015.html), the skywatching service [Slooh](http://www.space.com/19195-night-sky-planets-asteroids-webcasts.html), or here at TIME. You can also tweet to NASA astronomer Mitzi Adams (@NASA\_Marshall), who will be taking questions using the hashtag #eclipse2015 from about 6 a.m. to 8 a.m. EDT. It will be the third lunar eclipse in a series of four known as a “tetrad,” following those in April and September last year. The final one of the series will occur on September 28, 2015.

Read TIME Science Editor Jeffrey Kluger’s explanation of the phenomenon here.](http://time.com/62125/blood-moon-lunar-eclipse-cosmic-jaguar/) ## Transcript This evening sky watchers will get a chance to see a total lunar eclipse, one of four that should occur in 2014. But what exactly will they be seeing? A total lunar eclipse occurs when the earth moves between the light of the sun and the moon. Blocking the light that would ordinarily illuminate the moon. The moon isn't blotted out completely, instead it glows in an eerie coppery red. That's because the Earth's atmosphere, which is mostly nitrogen, filters out blue light, allowing only red light through. That makes it was to the moon and gives us what is sometimes called a blood moon. The fact that there is four eclipses this year is actually unusual. And it's particularly unusual since they will all be visible from North America. Before the 20th Century there was a 300 year period where there were no eclipses at all. Tonight's sky show begins at about 2: 00 AM for east coasters, so if you are up late enjoy it. But if you miss it, the next one should be here in a few months. I'm Jeffery Kluger for Time Magazine. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3770720/lunar-eclipse-blood-moon-saturday/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3770720/lunar-eclipse-blood-moon-saturday/"},"headline":"How to Watch the Shortest Lunar Eclipse of the Century on Saturday","datePublished":"2015-04-03T16:58:47.000Z","dateModified":"2026-08-04T08:06:22.408Z","description":"The West Coast, India and parts of China and Russia will have the best view","url":"https://time.com/3770720/lunar-eclipse-blood-moon-saturday/","keywords":[],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt45a115f0ecf5b17e/698786a6a988ca727e6ad39f/lunar-eclipse.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Alex Rogers","jobTitle":null,"url":"https://time.com/author/alex-rogers/"}],"articleSection":"Science","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt45a115f0ecf5b17e/698786a6a988ca727e6ad39f/lunar-eclipse.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"APTOPIX Lunar Eclipse","caption":"APTOPIX Lunar Eclipse","creditText":"Wilfredo Lee—AP","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/science/","name":"Science"}},{"@type":"ListItem","position":2,"item":{"@id":"https://time.com/3770720/lunar-eclipse-blood-moon-saturday/","name":"How to Watch the Shortest Lunar Eclipse of the Century on Saturday"}}]},{"@context":"https://schema.org","@type":"VideoObject","name":"How a 'Blood Moon' Happens: TIME Explains","description":"Billions of people will be witness to this year's first '","thumbnailUrl":"https://cdn.jwplayer.com/v2/media/Fq7u3Vlp/poster.jpg?width=720","uploadDate":"2014-04-14T18:27:41.000Z","contentUrl":"https://cdn.jwplayer.com/manifests/Fq7u3Vlp.m3u8","embedUrl":"https://time.com/3770720/lunar-eclipse-blood-moon-saturday/","duration":"PT1M9S","potentialAction":{"@type":"SeekToAction","target":"https://time.com/3770720/lunar-eclipse-blood-moon-saturday/?jw_start={seek_to_second_number}","startOffset-input":"required name=seek_to_second_number"}}] ```
