This spectacular upside down rainbow was spotted in the skies over Rhyl .

The minor meteorological event was caught on camera by Emily eight-year-old Prendergast outside her home in Lon Hafren just after 7.45pm.

The images show the spectrum of colours facing the opposite way in the sky.

But experts say they are not actually rainbows.

In fact, the correct term for this meteorological phenomenon is a circumzenithal – or Bravais – arc. Unlike rainbows, where sunlight refracts through raindrops, circumzenithal arcs occur when sunlight refracts through ice crystals, held in cirrus clouds, in a specific way.

Circumzenithal arcs are relatively common and only occur when the sun is more than five and less than 32 degrees above the horizon.

The air also needs to be relatively still.
