SIGNS IN THE HEAVENS: Weather Phenomenon - Full Circle Rainbow Brightens Skies In Cookstown, Northern Ireland! [VIDEO]

March 10, 2016 - IRELAND - A bright full circle rainbow was seen over Northern Ireland on March 7, 2016.

A rainbow is a meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. It takes the form of a multicoloured arc.

Rainbows caused by sunlight always appear in the section of sky directly opposite the sun.  Rainbows can be full circles; however, the average observer sees only an arc formed by illuminated droplets above the ground, and centred on a line from the sun to the observer's eye. 

In a primary rainbow, the arc shows red on the outer part and violet on the inner side. This rainbow is caused by light being refracted when entering a droplet of water, then reflected inside on the back of the droplet and refracted again when leaving it.  In a double rainbow, a second arc is seen outside the primary arc, and has the order of its colours reversed, with red on the inner side of the arc.

SIGNS IN THE HEAVENS: Weather Phenomena - Rare Full Circle Rainbow Appears In The Skies Over Greenville, South Carolina!

This extremely rare full circle rainbow appeared over Greenville, North Carolina and was captured by Brad Hudson

January 17, 2016 - SOUTH CAROLINA, UNITED STATES - Yes it's possible to see them... when you are just up high!

This was the case of Brad Hudson, owner of The City Arborist in Greenville, SC.

When sunlight and raindrops combine to make a rainbow, they can make a whole circle of light in the sky.

But it's a very rare sight.

This rare sky phenomenon was captured on January 16, 2016.

Sky conditions have to be just right for this, and even if they are, the bottom part of a full-circle rainbow is usually blocked by the horizon.

That's why we see rainbows not as circles, but as arcs across our sky.

If you could get up high enough, you'd see that some rainbows continue below the horizon seen from closer to sea-level.

Brad Hudson with The City Arborist, LLC, a Greenville tree care company was at a 400-foot elevation when he snapped the full circle rainbow.


WATCH: In 2014, a perfect rainbow circle was filmed from the Skylon Tower Revolving restaurant at Niagara Falls, Ontario:
