Suspected meteorite terrorizes US Eastern Seaboard

Four fireballs, glowing blue and orange, were visible last night over the skies from Virginia to South Carolina, followed by the sound of an explosion described as being like thunder. Reports of hearing the noise were coming in from as far afield as Connecticut. There is currently no word from the US Space Surveillance Network as to what it could be, but it seems improbable that anything non-nuclear the military could put up could be heard over that kind of distance. The suggestion from the Naval Observatory that it was the second stage of Soyuz is, of course, plausible but later observations say that ended up near Taiwan. It would also have been hard to explain the color of the fireballs and the size of explosion through the Soyuz hypothesis. Other sources also claim the tracking rules out the Soyuz hypothesis. It therefore still seems likely to be a very big meteorite.

The next question would be what type of meteorite. This is not an idle question. The one slamming into the Sudan recently was (a) extremely big at an estimated 80 tonnes, and (b) from the extremely rare F-class of asteroid. If this new meteorite is also from an F-class asteroid, then it is likely associated with the one that hit Sudan. This is important as it means we might want to be looking very closely for other fragments yet to hit.

The colors are interesting and allow us to limit what the composition could have been and therefore where it came from. We can deduce this because anything slamming through the atmosphere is basically undergoing a giant version of your basic chemistry "flame test" for substance identification. We simply need to look up what metals produce blue, and in so doing we see that cadmium does produce a blue/violet color, with copper producing more of a blue/green. Other metals also produce a blue glow and tables of these colors abound, but some are more likely in meteoric material than others. For example, studies have been made on the cadmium content of different types of meteorites and meteorites in general.

Ok, what else do we know? The fireballs were also orange. Urelites, such as the Sudan impact, contain a great deal of calcium, which burns brick-red, not orange. This suggests we can rule out the same source, which in turn means we probably don't have to worry about being strafed the way Jupiter was with the Shoemaker-Levy comet (21 impacts).

It was just the Soviets testing the US's missile defense system prior to a nuclear first strike.

Stating the obvious since 1969.

The thing is, nobody is entirely sure what it was that was real. For every claim published so far, there's been a counterclaim.

Perhaps it is an early shard of the approaching Planet X compound (http://www.zetatalk.com)!
