Hello,
I have figured out the basics so far, but perhaps someone could help me figure out a bit more.
I observed this meteorite moving across the sky, looking like a low airplane glowing bright bright orange. from the american meteor site (http://www.amsmeteors.org/fireballs/faqf/#1), this likely indicates it was a slower moving rock containing sodium.
In about 3 seconds it traversed 5 degrees of arc, before winking out altogether at roughly an angle of 30 degrees to the horizon. Rock stops ablating around 2km/s, so I roughly estimate its height to be around 32km at a direct line of distance of 68km.
The object itself was moving at roughly 10 degrees below horizontal.
Using this, is it possible to find out how fast it was traveling when it first entered the atmosphere?
