    I am not exactly NASA nor am I an emergency bureau of Russia, but from what I hear it was 300 kilotons of explosive force.

    Escape velocity is 25,000 mph, so that's the minimum possible speed of an approaching meteor. Since Earth orbits the sun at 66,000 mph, it is conceivable that an object on an opposite orbit could approach at a speed of 150,000 mph. Add in an approach trajectory toward the sun and that makes the max more like 160,000 mph.

    Wasn't the factory just one impact, and there was at least one more? I've been also seeing pictures of an iced over lake or something with a circular hole.

    I would be interested to see how close the east-west and west-east paths shown below were to the Chelyabinsk, Russian meteorite and the Gold Coast, Australian fireball.

    Did 2012 DA14 hit something a long time ago or is it just balderdash?

    Again as I said before the numbers are all over the place now, just look at the wiki.

    Last year at about this time (14 Feb 12) there was a similar incident in Georgia, USA. Could this be the beginning of a new shower?

    No, not nearly so big.

    Thanks. that link states:
    "Not since 1908, when a space rock exploded over Russia's Tunguska River in Siberia and flattened 825 square miles (2,137 square km) of uninhabited forest land, has a meteor event been so devastating."

    I thought nothing was ever found of that "rock" so most believe it was a "dirty ice ball" and some few even think that it was a speck of anti-matter. If nothing can be found of this new Russian one, I bet it too was a "dirty ice ball."

    Since it appeared to fragment into a small number of significant size pieces, it would surprise me to find out it was ice rather than rock and metal.

    You're welcome. Cool, that speck of antimatter idea.

    I wonder if a search near that hole in the ice of a lake in the area will turn up a fragment or not.
