Total Lunar eclipse, Supermoon, Blue moon, Eclipse In Januvary
ON
Wednesday night, India will be in for a
treat with a rare lunar trifecta taking place. Consisting of a total lunar eclipse,
supermoon and blue moon
On the 31st, the moon will officially reach its full phase at
8:27 a.m. ET (13:27 UT). This is the second full moon to occur in a calendar
month, an event commonly referred to as a blue moon. Around the same time, the
full moon will be making an especially close approach to Earth, a phenomenon
popularly called a supermoon.
Ironically a blue
moon isn’t even blue. The term instead refers to when
there is a second full moon in a calendar month.
Lastly, the supermoon part
comes into play as the moon will be closest to Earth as it orbits around us.
While it will loom large in the sky it will in fact still be 360,198km away.
Super Blue Blood Moon 2018
The Blue Moon – second of
two full moons in one calendar month – will pass through the Earth’s shadow on
January 31, 2018, to give us a total lunar eclipse. Totality, when the moon
will be entirely inside the Earth’s dark umbral shadow, will
last a bit more than one-and-a-quarter hours. The January 31 full moon is also
the third in a series of three straight full moon supermoons – that is,
super-close full moons. It’s the first of two Blue Moons in 2018. So it’s not just a total lunar eclipse, or a Blue Moon, or
a supermoon. It’s all three … a super Blue Moon total eclipse!
The Blood Moon occurs because the Earth is passing between
the Moon and the Sun, which gives the Moon a reddish tint to it. It's caused by
light bending around the Earth because of gravity passing around a portion of
the atmosphere, more commonly known as a lunar eclipse.
A Blue Moon
combined with a Supermoon (when the Moon is at its closest point to Earth and
appears to be 14 percent bigger and 30 percent brighter than normal) the rare
phenomena is called a Super Blue Blood Moon happens. Supermoons generally only
occur once every 14 months and will not happen again until January 2019.
A blue moon is the second full moon in a
month. A supermoon is a particularly close full or new moon, appearing somewhat
brighter and bigger. A total lunar eclipse — or blood moon for its reddish
tinge — has the moon completely bathed in Earth’s shadow.
“I’m calling it the Super Bowl of moons,” lunar scientist
Noah Petro said Monday from NASA’s Goddard Space Flight Center in Greenbelt,
Maryland.
The moon will be closest to
Earth on Tuesday, 359,000 kilometres. That’s about 2,400 kilometres farther
than the supermoon on Jan. 1. Midway through Wednesday’s eclipse, the moon will
be even farther away, 360,200 kilometres — but still within unofficial
supermoon guidelines.
The event is causing a buzz because it
combines three unusual lunar events -- an extra big super moon, a blue moon and
a total lunar eclipse.
"It's an astronomical trifecta," said Kelly Beatty, a senior editor at Sky and Telescope magazine.

A blue moon refers to the
second full moon in a month. Typically, a blue moon happens every two years and
eight months.
WHERE WILL THE ECLIPSE BE
VISIBLE?
For this month’s super blue blood moon, the best views will be
for people on the northern part of North America’s West Coast, as well for
viewers across China, Japan, and most of Australia. Observers there will
witness the entire eclipse from beginning to end during the early morning hours
of January 31.
WHAT HAPPENS IF I CAN’T
SEE TOTALITY?
If you get clouded out or
it’s daytime where you are at the time of the eclipse, you can still tune in to
the show online via webcasts such as the Virtual Telescope
Project and Slooh. And if you happen to miss out this time
around, the next total lunar eclipse will arrive on July 27 and will be visible
from Asia, Australia, Africa, Europe, and South America.
