A rainbow opposite the rising sun over the A465 at Resolven.
This is an image not often seen as there was no rain to form a rainbow
the following text from Google:
“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 circular arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the sun.”
