I captured this when taking a pic of the night sky over a cow pasture

I stopped to take a picture of the night sky over a cow pasture with my iPhone. The moon was very bright. I didn’t realize what I had captured until I got home and reviewed the photos that I took. I took pics before and after the object that I captured. The sky was completely clear over the totally clear cow pasture. My phone records, the date time and exposure I used which I can provide. I’m not sure exactly what I captured but it certainly does look to be like UFO of some sort. I don’t know what else it could be.
