ERETZ YISRAEL – Blue Supermoon Eclipse

Today’s Blue Supermoon Eclipse Will Begin Locally at 5:18 p.m. and End at 6:08 p.m.

JPOST: Weather permitting, Israelis will have the opportunity early this evening to partially view a rare “blue moon total eclipse,” along with others in the Middle Eastern parts of Asia, North America, Alaska and the Hawaiian islands.

Today’s lunar phenomenon is special for three reasons.

Firstly, it is a total lunar eclipse, where the Earth passes exactly between the Sun and the full Moon, casting a total shadow onto its lunar neighbor.

Secondly, it is the second full moon of the calendar month, commonly known as a “blue moon.” The first one was on January 1 and 2, depending on the viewer’s time zone.

Thirdly, it’s the third in a series of supermoons – when the moon is closest to Earth in its orbit and therefore appears larger and is about 14% brighter than usual.

Supermoons can be either full moons, where the entire disk of the moon is visible – or new moons, where only a sliver of the newly emerging disk is visible.

According to the website, blue moons are not as rare as the old saying “once in a blue moon” implies; they happen about once every 2.7 years.

But today’s combination cosmic event, consisting of a total lunar eclipse occurring on a blue moon, is relatively rare; the last time it happened was 152 years ago. Occurrences are irregular, however – the next time is only about 11 years away at the end of 2028, followed by another occurrence about eight years later at the beginning of 2037.

The super blue moon will pass through the Earth’s shadow to give viewers in the right location a total lunar eclipse. Here in Israel, it will only be a Penumbral Lunar Eclipse, where a significant crescent will still be visible before the shadow begins diminishing in size and the full moon reappears.

According to NASA, while the Moon is in the Earth’s shadow, it will take on a reddish- orange tint, known as a blood moon. The colored light is sunlight that has skimmed and bent through Earth’s atmosphere and passed on through space to the Moon.

Unlike a solar eclipse, a lunar eclipse can be viewed with the naked eye safely, without protective eyewear   [Article and Photo from JPOST (link above)]

If you live in the western part of North America, Alaska, and the Hawaiian islands, you might set your alarm early the morning of Wednesday, Jan. 31 for a lunar trifecta: a pre-dawn “super blue blood moon.” 

Beginning at 5:30 a.m. EST on Jan. 31, a live feed of the Moon will be offered on NASA TV and You can also follow at @NASAMoon. Weather permitting, the NASA TV 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.
“For the (continental) U.S., the viewing will be best in the West,” said Gordon Johnston, program executive and lunar blogger at NASA Headquarters in Washington. “Set your alarm early and go out and take a look.”
The Jan. 31 full moon is special for three reasons: it’s the third in a series of “supermoons,” when the Moon is closer to Earth in its orbit -- known as perigee -- and about 14 percent brighter than usual. It’s also the second full moon of the month, commonly known as a “blue moon.” The super blue moon will pass through Earth’s shadow to give viewers in the right location a total lunar eclipse. While the Moon is in the Earth’s shadow it will take on a reddish tint, known as a “blood moon.”

Did anyone see the eclipse??
Or the blood moon??
I looked and the moon was full and large but that’s all.

In New York I saw the beginning of it, it was only a yellow-orange tint, not as dark as I expected. I saw the top part start to have a dark shadow, but the moon was setting in the west and it dipped behind some houses after a few minutes and I couldn't find it again so I watched online.

There was no eclipse visible over Israel. It ended just before the moon rose here.
