Super blue blood moon: NZ to witness extremely rare event

Blue Moon to appear over Qatar sky on January 31

Blue Moon to appear over Qatar sky on January 31

This is usually when the show really gets started.

At the same time, the moon will be passing through the darkest part of the Earth's shadow. States such as Montana, Wyoming, Utah, and Arizona are far enough west that the moon is above the horizon for totality. In New Jersey we will see only a small portion of the eclipse.

Secondly, it is the second full moon of the month.

On the last day of January, the Moon will arrive full moon phase; where it will be the second full Moon during the month.

The moon's orbit is tilted by about 5 degrees relative to the earth's orbit. "They expect to see something spectacular - and it is incredible even if that might be true of most full moons when viewed on the horizon". Because the moon's orbit is inclined to Earth's orbit and Earth's shadow at the moon's distance only covers a little bit of sky (just 2.5 degrees), the full moon nearly always misses the target, sliding either above it or below it.

"It is going to be a historical moment because it is a coincidence when blue moon, red moon and full lunar eclipse will take place at the same time and on the same date", said chief Pakistan Meteorological Department (PMD), Dr Ghulam Rasul told The Express Tribune on Saturday. The result: the moon appears larger than normal and NASA is predicting this one will be 14% brighter than usual.

To see the phenomenon, you need to be on the night side of the earth; this eclipse will be visible mostly in Asia, Australia, the Pacific and North America. Johnston said another lunar eclipse will occur on January 21, 2019, that will be visible throughout the country. Though not uncommon separately, this is the first time all three will happen at the same time since 1866, according to NASA. Unlike pigs flying, blue moons themselves are not all too rare; they come every 2.7 years. Rather, it's lit by light filtered through the Earth's atmosphere, via the same spectral filtering - a mechanism known as Rayleigh scattering - that causes red sunsets and sunrises. Sunlight squeaks around the edges of the Earth because the atmosphere acts like a prism and bends or refracts sunlight into the shadow.

While being "super" may be in the eyes of the beholder, a blue moon is much more straightforward.

"Supermoon" is a popular term for what astronomers call a "perigee full moon".

The term "blue moon" has nothing to do with color.

A "blue moon" is a second full moon that occurs in a single month. The third is now due to arrive at the end of the month. He says that it's important to keep in mind that the moon is a moving object: "It's a balancing act between trying to get the right exposure and realizing that the shutter speed typically needs to be a lot faster".

Finally, this full moon will also be a "blood" moon. But that is not the definition we use today. The next time will be July 27, though that eclipse won't be good from Florida either, he said. The moon's orbit is not perfectly circular, meaning its distance from Earth varies as it goes through one cycle. At its closest point it is about 225,000 miles away. This is why the moon is called "red moon". The first supermoon of January occurred on January 1 and the second will fall on January 31.
