this image was taken in my truck in November, 2017. It was taken by an Apple 8 cell phone camera while crossing a bridge. We took 7 or 8 photos trying to get a good image of a sunset and found this on only one image when viewing the photos. It was not visible to our naked eyes. Please help ID. I am a 67 y/0 psychotherapist in private practice and have been attempting to get a positive ID on this image. Previous attempts have been unsuccessful but I have gotten a few interesting responses such as "a stairway to heaven" and a portal to another dimension. I am not ready for either so I am soliciting more responses. I am in need of help in ID ing this image.
