Sun-bow?

 So, I was driving home last night, up the M1 - and in the distance I saw what Tim Wheeler would call a 'Shining light' - it was just shimmering and I had to get the phone out and take a photo. One of those times when you wish you had your proper camera with you....

As I drove on, it seemed to start extending on the right hand side, and lo and behold; it merged itself into what can only be described as a 'Sun-Bow'. There was no rain - anywhere - it was just 'formed' and reflected off the clouds...

I have never seen a 'sun-bow' before - and potentially never will again. Quite fascinating. As soon as it was there, it was gone.
