(meteorobs) Re: A (somewhat) unusual meteor?
Hello List,
Another interpretation is that a meteorite is being tumbled and presenting different streamlines to the air smaller means less area exposed to ablation and less illumination . A larger face of the meteoroid can offer more material to the atmosphere for ablation , hence a larger fireball. In the speeds or entry we see a "wap wap du wap"of larger and smaller incandescence.
One more alternative is that nodules of softer material-- such as triolite or graphite-- are being exposed and burn faster and brighter then the nickle-iron mass producing more incandescence.
Just a thought
Regards,
Elton
