Plasma ball of fire materializes at exactly same time as thought of previous UFO sightingI had been visiting with a friend who was staying at hotel very close to Sea World in Orlando. We had been hanging out by the hotel pool. My friend took my wife to show her where the restrooms were. They weren't gone 2 minutes when I looked up at the sky and saw what appeared to be a ball of plasma or fire, yellow-orange in color. The object seemed to materialize, travel a short distance and then de-materialize 3-4 seconds later. It appeared to be approximately 1000 ft. high and about 500ft. In front of me to the North above FL-528 (Beachline). It was moving to slow and low to be a meteor. Estimated size approximately 15-20 ft. In diameter. Behind the object there seemed to be a disturbance in the atmosphere maybe 30 ft. long, and appeared to have a heat shimmer effect. I don't believe it was ball lighting because there were no storms in the area and even humidity was relatively low for Orlando, this time of year.An interesting couple of notes to this sighting. This 'ball of plasma?' appeared at the exact moment in which I thought of a UFO sighting witnessed by a friend of mine that occurred in a neighborhood less than 2 miles from this one. Also, there is a major defense/aerospace contractor located less than 2 miles from my sighting.I will send an image which I pulled off the internet that very closely represents the object that I witnessed.
