Fireball!

The red ball is likely the heat glow of the object it hit, which doesn't mean an explosion, but incandescence. Lightning itself is glowing because of the incandescent effect of 30,000K temperatures on the gasses of the air + the refraction of air itself. Many of the objects in an around our houses are very rich in carbon, and carbon glows red, orange and yellow depending on the temperature. Add in the very white effect of lightning at close range and wallah, you got yourself a pretty red/white "explosion". That is my guess!

Isn't the "incandescent effect of a 30,000k temperaturre object" one portion of what comprises an "explosion"? Or to phrase it another way, if that wasn't an explosion, then what is? It seems like it was a rapid expansion of air which produced a burst of light and sound... AKA an explosion(?)


Absolutely correct, I used sloppy language, I meant it wasn't combustion (such is the meaning of explosion when we normally talk about it). Thunder is most surely the result of an explosion of air expanded by plasma. Good catch!

If this is Florida, which I believe it is, it is also there to dissuade the gators. >> ^Sagemind:

Ya, it's just there to keep the leaves from falling into the pool...

Is her little atrium just poorly designed or is there just some open area I can't see since there was rain coming in.

I think it's all mesh. I can see tiny ripples in the material as the wind blows.

What the hell was that?

Just a wild guess, I'd suggest lightning?
When freeze-framing you can definitely see the lightning bolt, but the resulting fireball looks like it hit something combustible.


Just hitting a tree can result in a fireball, which I think is the case here.

Asteroid 2012KT42 passes earth closer than geosync satellite

Sagemind says...

Just a few decades ago, most scientists thought the idea of asteroids crashing to Earth to be ludicrous. Today, this same idea isan accepted fact. Not only do asteroids fall to Earth, but more are being discovered every day. Yesterday, one of these newly-discovered asteroids just buzzed Earth. Coincidentally, this comes just days after NASA said that thenear-Earth asteroid population was larger than previously thought.

Monday, asteroid 2012KP24, which is about 69 feet across, came within about 32,000 miles ofEarth, well within the Moon’s orbit. Yesterday, asteroid 2012KT42 came within a mere 9,000 miles of Earth. In a fact thatmay be especially disconcerting tosome, the time span between discovery and close approach for the second asteroid was only a day! Talk about next to no warning.

Now for the good news: the asteroids were small and even if either were to collide with the Earth, they may not even have been large enough to survive the descent through the atmosphere,burning up in a spectacular fireball instead. Still, though, the fact that an asteroid can sneak up on us out of space with only afew days notice is the troubling part of this whole situation.

It is a perfectly logical idea that an asteroid could, one day, destroy life as we know it on Earth. The good news is that scientists are busy developing plans to avert doomsday. The problem is this: in these doomsday prevention plans, the time frame for a response is typically, at the least, months, notdays. With only a couple of days notice and with current technology, it would probably be impossible to do anything to save the planet and our civilization.
