@khirsch@sangwann I got lucky. I was on a photo safari with the car and saw this rainbow on the other side of the dike. That day there was no sign at all of a rainbow coming and this it was the only one I saw . . I had to park the car , crab my camera and run over the dike to the water side. Lucky, (S)he still was there . Soon after I did two pic.`s it was gone . Did n`t see a second one.
