The following exert is an eye witness statement. Please read into it what you will. This has been reported to mufon who I am sure are investigating:
Taking photos of sunset, didn’t notice white disc until i was reviewing them a year later. it didn’t move that i know, but there were black spots when i zoomed in on the picture. i’m just looking for an explanation. it looked unnatural to me, and i’m always watching the sky as i live on the beach. when the sun set completely, it wasn’t visible.
