Picture taken, object cannot be explained. No reflection possible we can explain. Have photo to share

My wife and I were visiting J. W. Marriott resort in Palm Springs California.  After we had lunch, we strolled around the outside area just east of the lake they had.  My wife posed for a few pictures and I shot five pictures of the resort with the mountains in the distance.  After I finished taking pictures, I looked at the ones just taken.  About 1:11pm, according to the built in timer on the photos.
Much to my surprise, one of the pictures had an image I immediately showed my wife.
I asked her, what do you think this is at the top upper portion in the sky?  Both my wife and I cannot explain it.  There was no reflection we could ascertain that would have made this appear in the picture.  The short time only seemingly caught on the picture.  If this was real, I cannot explain it.
I can forward you the picture if you respond to me.
