 NASA TV to air live coverage of rare lunar eclipse

Sky-gazers are in for a rare treat Wednesday, Jan. 31, when three celestial
events combine to create a super
<https://www.nasa.gov/feature/super-blue-blood-moon-coming-jan-31> blue
blood moon. NASA Television and the agency’s website
<https://www.nasa.gov/live> will provide live coverage of the celestial
spectacle beginning at 5:30 a.m. EST.

Weather permitting, the broadcast will feature views from the varying
vantage points of telescopes at NASA’s Armstrong Flight Research Center in
Edwards, California; Griffith Observatory in Los Angeles; and the
University of Arizona’s Mt. Lemmon SkyCenter Observatory.

This event offers a rare opportunity to see a supermoon
<https://moon.nasa.gov/observe-the-moon/supermoon/>, a blue moon and a
lunar eclipse at the same time. A supermoon occurs when the Moon is closer
to Earth in its orbit and appears about 14 percent brighter than usual. As
the second full moon of the month, this moon is also commonly known as a
blue moon, though it will not be blue in appearance. The super blue moon
will pass through Earth’s shadow and take on a reddish tint, known as a blood
moon <https://apod.nasa.gov/apod/ap151003.html>.

A total lunar eclipse
<https://www.nasa.gov/audience/forstudents/k-4/stories/total-lunar-eclipse>
occurs
when the Sun, Earth, and a full moon form a near-perfect lineup in space.
The total phase of the eclipse will last 1 hour and 16 minutes. The whole
process will take more than four hours.

If skies are clear, the U.S. West Coast, Alaska and Hawaii will have the
best view of totality, from start to finish. For the eastern U.S. and
Canada, a clear view will be limited as the Moon sets and the Sun rises
during the early stages of the eclipse.

The last total lunar eclipse occurred Sept. 27-28, 2015. The next total
lunar eclipse visible across North America will occur Jan. 21, 2019.

The Jan. 31 eclipse is the third in a series of supermoons in December 2017
and January 2018. Watch the Supermoon Trilogy <https://youtu.be/A4v5YgC9vkE>
