Or some weird lens flare or camera distortion, of course.
TUS has seen a lot of "UFO" photos like these and they aren't the best reports ever as there was no actual eyewitness to these UFOs. However, this one in particular looks like it might be something. Check out the photo and witness description submitted to MUFON and judge for yourself!
In my back yard taking photos of deer. It was dark - I took 3 separate photos within less than a minute. Didn't notice anything until I was reviewing the photos. The second picture of the three I took had a VERY NOTICEABLE odd light form. I was too busy focusing on the deer and didn't notice anything until I was reviewing my pictures. There was no actual "sighting." The light form was in the second photo.
As always, if you've seen anything strange in the Texas sky of late, report your sighting!
