The photographer was taking cloud images at the time and was not aware of anything unusual in the sky.
The following is the unedited and as yet uninvestigated report filed with MUFON.

As a relaxing hobby, I enjoy taking pictures of various cloud formations, storms etc.

“I parked in the lot across from a Walmart to snap a few cloud photos. I did not see or notice any planes /crafts or lighting in the sky, all normal. Only later that day, as I reviewed the photos, I found the ufo? object on one of the photos.”
