I have seen ball lightning twice in my 6 + decades.
The first time was in my folks kitchen, about 40 years ago. There was a pretty respectable thunderstorm at the time, and Dad had just gotten up from the supper table to get a jar of pickles from the fridge. There was a loud explosion, and then this amazing ball of blue light, slightly smaller than a basketball, came out of the gas range, passed in front of Dad, went about ten feet across the room to the sink, stopped, turned about 100 degrees, went about 8 feet to the refrigerator on the far wall, and went into it ? The thing took about 3 seconds to make the trip, so while it wasn't hovering, it wasn't moving that fast either.
Dad expressed his joy for not being at the refrigerator yet !!! Lightning had either hit the phone service box on the outside wall, or followed the phone line to it, then jumped to the fan vent for the range hood. The fan in the hood, the stove, and the refrigerator, as well as the lights and house electrical system were unaffected, but both phones were toast, and the service box was lying about 30 feet from the house.
The second time was about ten years ago. We were on the hi way, doing about 60 mph on a cloudy day, when we were passed by a ball of greenish light that had to be at least 15 feet in diameter. As it got by us a quarter mile or so, you could see it was kind of bouncing up and down. It was around the three cable hi line next to the road, and was really moving, because I doubt it took 8 or 10 seconds to disappear over the hill a mile and a half away.
