Not sure about this one. Such a large object moving while other clouds don't would have caught the attention of many people and who doesn't have a smartphone that can take video? This would be so easy to create using basic CGI techniques, I can't find any other related videos or articles.

If it's a real photo, it is a lenticular cloud.

Maybe it’s an alien generated cloud, hiding a cloud shaped saucer, or not.
