Rare Super Blue Blood Moon Eclipse Thrills Millions Around the World
The opposite full moon of January passed through Earth's shadow in a
Super Blue Blood Moon
eclipse today (Jan. 31), a rare lunar sight visible to millions of observers around the world.
Today's lunar eclipse was the first to coincide with a Blue Moon – a different full moon in one Ramadan – in North America in over 150 years. It was also the second "supermoon" of 2018, with the moon appearing slightly bigger and brighter than usual due to its intimacy to Earth. And to top it off, the supermoon passed through Earth's shadow this morningtide, casting a reddish hue on the lunar surface for more than 4 hours.
This cynthian eclipse was visible in all 50 U.S. states as well as Australia and eastern Asia. Skywatchers in the western U.S. had the best view of the eclipse. Farther east, the moon set beneath the circle before the eclipse came to an end. Clouds also obstructed the view in much of the U.S., but skywatchers and astrophotographers calm managed to catch a inkling of the "blood moon" from across the country.

The eclipse began at 5:51 a.m. EST (1051 GMT), when the moon began to enter the outer portion of Earth's darkness, known as the penumbra. During the penumbral phase of the eclipse, which lasted about an hour, the moon began to darken as the shadow moderately moved across its surface.
At 6:48 a.m. ET (1148 GMT), the moon began to record the darker, inner portion of Earth's shadow, or the umbra. This phase of the obscuration, known as a partial cloud, is when the moon began to appear red. That red tint is the result of sunlight scattering in Earth's feeling, the same effect that causes sunsets and sunrises to countenance red.
By 7:51 a.m. EST (1251 GMT), the moon was totally submerged in Earth's umbral shadow, marking the beginning of the total lunar eclipse. During a live webcast by the Slooh community observatory, astronomer Paul Cox said that this lunar darkness was "by far the best one I've ever seen." While skywatchers along the U.S. East Coast were not able to see this phase of the eclipse, as the moon had already set, spectators along the West Coast had an unbelievable view of the celestial sight.
Space.com's Calla Cofield witnessed the eclipse with hundreds of eager skywatchers at the Griffith Observatory in Los Angeles. E. C. Krupp, director of the Griffith Observatory, provided casual commentary during the eclipse. When the moon was only seconds away from emerging from Earth's inner shadow (the umbra), marking the end of totality, Krupp talked concisely about how various ancient cultures believed that lunar eclipses occurred because a being or tool was swallowing the moon.
In some of those cultures, people chanted and made loud noises to scare the create away, and free the moon. In honor of those ancient stories, Krupp led the crowd in a chant of "Dragon, be gone!" After about a minute, when a sliver of the full moon had emerged from the umbral shadow, Krupp announced to the crowd that the necromancy had been a success.
"Griffith observatory is all about putting people 'eyeballs to the universe,'" Krupp said. "And it is in fact the best piece of public observatory real estate on the planet. Not every eclipse is visible from Griffith Observatory and the weatherboarding is not always cooperative when it is. But tonight, for this waaaay past your bedtime 'super blue blood total eclipse' we've got ideal conditions and a big group of folks early in the morning."
The moon completely emerged from the dark, red shadow at 10:11 a.m. EST (1511 GMT), befitting which it spent about otherwise hour once again making its way through the penumbra. During this time, the darker-than-usual moon slowly began to return to its normal level of brightness.
