What an amazing video. I'm not convinced that was ball lightning.

The videographer's says:

I'm not sure if the ball was even the Ball Lightning phenomena, but chances are that it was. It appeared during a thunderstorm and it had all the characteristics of Ball Lightning. The ball was extremely large and flickered orange/yellow. At one stage it took on a disc like shape, but I like to think to myself that it was Ball Lightning, not an alien or something ridiculous.
