It appears to be lit by the setting Sun. It could be an odd contrail- certainly the speed and motion are about right. But it's got an unusual head for a contrail.

Re: [meteorite-list] Huge Daylight Fireball Video?
Yeah, I though it odd Hence the ? mark. I did notice the sun setting (or rising) and thought this could possibly explain the orange glow of the fireball if it is contrails reflecting the orange glow from beyond the horizon. Still though, if it were a contrail from an airplane wouldn't it persist in the air longer than it does? The tail of this fireball seems to stay the same length through out the video and not stretch out across all the way across the sky like a contrail would. Why is that? Don't contrails from planes tend to get larger further from the aircraft as the trail expands and dissipates in the air? This video shows a tapering of the short contrail seemingly getting smaller the further away from the object. What would cause that? Or is it only seeming to taper off because of the haze in the air explaining why the longer contrail is not visible as well?

Re: [meteorite-list] Huge Daylight Fireball Video?
In fairly still air, contrails persist until they evaporate. How long that takes depends on the humidity and water content of the air. I use contrail patterns during the day as a tool to assess probable astronomical seeing conditions that night. I'm looking for still, dry air. I know that's what we've got when airplanes leave no contrails, or leave contrails that only persist for a very short distance behind the plane- like what the video shows. Here over the central Rockies, such short contrails are very common. Contrails normally form off the trailing surface of the wings, and spread out with distance. In still air, they may spread very little, and appear to taper away again at the far end. But what you usually see then is a small start, some broadening, and then the taper begins. This thing in the video seems too large at the start, which is why I speculated that something was being vented. That said, it's also possible the problem is optical. The camera optics don't seem very good, and the image doesn't seem well focused. So the apparent blob of material at the head might just be an optical aberration of some sort.

The tail of this fireball seems to stay the same length through out the video and not stretch out across all the way across the sky like a contrail would. Why is that? Once right after sunset, I saw what appeared to be a very short comet hanging in the sky, low on the horizon. It seemed to be not moving and I thought perhaps it could be a comet. So I got out my 14X100 binoculars and peaked at it. What I could barely make out was a jet airliner just a hair beyond the trail. It appeared to be traveling obliquely away from me. I then could make out slow motion and the contrail never got bigger than about half of a small finger nails width at arms length. There was some foreshortening going on here and probably with the video's object as well. Have someone hold a yard stick perpendicular from you and it will look like a yard in length. then have them hold it with it's end towards you and slightly askew and it will appear very short. at long distances, the motion will become difficult to notice.

Re: [meteorite-list] Huge Daylight Fireball Video?
This thing in the video seems too large at the start, which is why I speculated that something was being vented. Another thing to consider is that if the object is appearing slightly askew and going away from the observer, details at the beginning can blur in with details further on back so you aren't able to focus on anything in particular, but rather a sum of what's happening. Let's say the blob formed a hundred or two feet back, maybe an expanding contrail will blot out the thinner part at the head? geozay **A Good Credit Score is 700 or Above.

I'm now convinced, despite what it looks like, we are looking at the contrails of a distant jet liner traveling away from the observer. Pretty much like what I described earlier when I took out my binoculars for a better looksy. GeoZay **A Good Credit Score is 700 or Above. See Yours in Just 2 Easy Steps!

Re: [meteorite-list] Huge Daylight Fireball Video?
Combination of bad optics, dry air, hazy day, and setting sun equals fireballs that last more than 4 minutes No wonder it looks like a fireball. You can add on to the above that the object was traveling away from you. At night you will have folks seeing stationary lights that suddenly go out when the plane is coming towards you. I use to have my observatory in the mountains near Descanso, CA (near San Diego). The flight path from the east went right over me. Quite often you would see small and large planes turn on their landing lights momentarily just for some reassurances as to where the mountains were...then shut them off.

Re: [meteorite-list] Huge Daylight Fireball Video?
That makes sense... I didn't realize that contrails dissipated so quickly in dryer air. But it makes sense if the air is more humid that the contrail would persist longer. The optical aberration seems logical enough too and could explain the seemingly larger leading edge.

Re: [meteorite-list] Huge Daylight Fireball Video?
I agree with Chris: this to me is a short aircraft contrail lit by the sun. I see no reason at all to think of a meteoric fireball.

Re: [meteorite-list] Huge Daylight Fireball Video?
It keeps surprising me that contrails, in this age of ubiquitous aircraft traffic, are still confused with fireballs so often. Most people never look up. An appalling percentage of adults are unaware, for instance, that the Moon can be seen during the day (something like half of adults in the U.S.) Now you put a jet near the horizon at sunset, so you get something too bright to miss, and of course too far away to make any sound, and I guess it's not surprising you get some people who believe they are seeing something extraordinary.
