Partial Lunar Eclipse- April-26-2013 Seen in chennai

The full moon will get a tiny bite taken out of today as it undergoes one of the shallowest and shortest partial eclipses of this century.

A lunar eclipse occurs when the sun, Earth, and moon align. During total lunar eclipses, the entire moon is engulfed in Earth's darkest shadow. But during partial eclipses, the moon never completely goes dark or turns red—only a portion of its disk appears to go dim.

Northern Hemisphere observers can watch Lunar Eclipse Friday

The full moon will get a tiny bite taken out of it tomorrow as it undergoes one of the shallowest and shortest partial eclipses of this century.

While North America will be left out of the sky show, much of the Eastern Hemisphere can see Earth's shadow brush across the outer half of the moon's surface over the course of the four-hour event. 

All the stages of the eclipse will be visible across the Indian Ocean, central Asia, western Australia, Africa, and Europe.

Because only a tiny fraction of the moon's disk will dip into the darkest shadow cone, the entire partial eclipse phase will be a challenge to observe, lasting less than a half hour for viewers, Hammergren said.

"This eclipse is distinguished, or undistinguished, by being the second shortest partial eclipse of the moon in the 21st century, lasting only about 27 minutes," he said.

When is best to watch?

The most readily visible part of the eclipse will begin at 3:54 p.m. ET (00:30 AM IST Aprox), just as the moon is straight overhead for observers in the Indian Ocean.

The deepest and most interesting part of the eclipse—during which Earth's shadow will fall on less than 2 percent of the tiny sliver of the moon's disk—occurs at 4:07 p.m. ET (00:40 AM IST Aprox.) and leaves the umbra at 4:21 p.m.

The last time such a small partial lunar eclipse occurred was in 1958, and another one like it won't occur until 2034.

But don't fret: Later this year, two more partial lunar eclipses will be visible on May 25 and October 18.

Sony's 4K Has Arrived, Pre order starts

Just a few mere months ago at CES 2013, Sony debuted its line of 4K TVs designed to bring the cinematic experience right into your living room. Well, get your living rooms ready because 4K is on the way!

Our 55″ and 65″ 4K Ultra HD TVs will be available for pre-order beginning April 21 for $4,999 and $6,999, get the scoop here.

The thing about 4K is that you need to see it in person to truly experience and understand what it is all about. A photo on the Internet or a short video clip on YouTube just doesn't do it justice. Some of you might have seen the 84'' (diag) 4K TV in select Sony Stores last fall. But if you've been dying to see what the 65″ and 55'' Class 4K Ultra HD TVs look like in real life, you're in luck.

Starting today, six Sony Store locations (see below) will be the first to feature the TVs and will be offering in-store demos of true 4K and enhanced (upscaled) video.

• Century City, Los Angeles CA
• South Coast Plaza, Costa Mesa CA
• Houston Galleria, TX
• The Forum Shops, Las Vegas NV
• 550 Madison Ave, New York NY
• Stanford Shopping Center, Palo Alto CA

If you do get a chance to get a 4K demo, please share your experience! Tweet us @SonyElectronicsor @SonyStore using the hashtag #Sony4K and tell us what you thought.
