trix I can see a very faint line of a wire running through it from left to right.
We have a few of those on electrical wires near a small local airport. They warn the pilot of the wires but also guide the pilots to the run way.
I can see why it doesn't show up in 2 of the still...
There's an airport but it's not really near so I cant see that airplanes would need to be warned of powerlines. Also, if this was on a powerline it couldn't just disappear on those other stills. Also, it got bigger. Also...... it's driving me crazy! LOL!!
Homely, thanks, but now I'm really puzzled. It has definitely got bigger and as Trix says, it's only on one of the stills. My next job is to go to Googlemaps to look for an airport.
It can't be a hot air balloon because it's not moving and if it had run out of gas it would come down with a bang! So I reckon your first guess was right, it IS a UFO. After all, WE can't identify it. LOL!
I think I need to go back to school..... didn't know about purple martins.
Trix, I really like this cam. If you wait long enough you see plenty of bird feeders and different views.
