Curious if anyone has seen something like this before, first time I've ever seen anything like it
Not the greatest pic but basically a rainbow-like colouring stretching along under the clouds - looks far more impressive and weird in person.
A low bow!
Just to do with the angle/elevation of the sun.
The lower the angle/elevation of the sun, the higher the rainbow will appear...and vice versa.
Pity I didn't have a better camera it looked very odd - an almost alien glow that stretched a fair bit, looked cool anyway!
