I had taken a number of photos that day from the deck in my backyard. i was experimenting with my new camera and was taking lots of pics. i only now just got to the pics i'd taken around that time. i didn't notice the blurred object behind the aircraft until i looked at the images. it could have been there but i was focused on the aircraft and didn't notice it at the time. it was a really bizarre sky/cloud cover and was interested in getting some good shots of some big airplanes with that backdrop. obviously it wasn't a good day for that.
