'Fire rainbow' caught on camera
The video was filmed Jan. 9 over the city of Lecce.
The phenomenon is caused by light from the sun or moon refracting off plate-shaped ice crystals suspended among the clouds in the atmosphere.
It is nicknamed a "fire rainbow" despite being neither a rainbow nor fire-related because the halo sometimes manifests in a way that resembles flames.
This beautiful heart-shaped fallstreak hole appeared in the sky of Houston, Texas on January 17, 2016 and baffled many skywatchers.

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

The jaw-dropping scene was captured by Mia Heikkilä, who later posted the picture on the Space Weather website.
'People gave hints to look if the pattern matches the local map. And there it was! Exact reversed light map of Kauttua, Eura, on the sky. Now I call it #LuxEura,' she wrote.
It may look like a scene from the X-Files but the explanation is more terrestrial.
The phenomenon, known as light pillar, appear when artificial light or natural light bounces off the facets of flat ice crystals in the air, producing luminous columns in the sky.
Light pillars are relatively common in cold, Arctic regions and most people see them from the side, where they look like towers that reach into the sky.

Known as KIC 8462852, or Tabby's star, it has been baffling astronomers for the past few months after a team of researchers noticed its light seemed to be dipping in brightness in bizarre ways. Proposed explanations ranged from a cloud of comets to orbiting "alien megastructures".
Now an analysis of historical observations reveals the star has been gradually dimming for over a century, leaving everyone scratching their heads as to the cause.
The first signs of this space oddity came from NASA's planet-hunting Kepler space telescope, which continually watched the star's region of the sky between 2009 and 2013. Most planet-hosting stars show small, regular dips in light when their planets pass in front of them. But Tabby's star dipped erratically throughout the four years, sometimes losing as much as 20 per cent of its brightness.

I mean look at the pictures and the video. They are overwhelming.
Sun dogs are either caused by the refraction of light on plate-shaped hexagonal ice crystals in high and cold cirrus or cirrostratus clouds or drifting in the air at low levels like in these pictures.
