4 objects not visible to the naked eye, flying around odd vertical "rainbow."Driving home at 5pm headed towards the city from Elm Hill and 40-W I saw a small vertical rainbow in the sky. I pulled over to take a few pictures, since the vertical sliver of rainbow was something I had never seen. When looking at the camera screen I noticed 4 objects flying around the" rainbow".I looked without using the camera and could not see the objects with the naked eye. I once again looked at the screen and the objects were still moving around the "rainbow." I did this several times with the same result.I cleaned my lens, as well as checked my camera by taking photos of other things in the area. This was not a dirty lens. The objects could be disc shaped but it is hard to tell. I have a series of photos.
