OOpppps, got the date wrong, Fri 21st(not22nd). sos sorry.lol.
The answer to the photo question of what it was??=
Some years ago I photographed FROST on the roof of my car, zoomed and cropped a part of the pattern that the FROST had made. Later playing with the colour changes settled on what happened.
So there you are answer FROST.
Did anyone guess right???.
