    Wow, that's pretty close!

    Another report puts it at just outside of Geosyn. Sat. Orbits, so I'm not sure which is correct.
    In any case Southern Hemi observers with appropriate equipment might be able to catch it briefly at magnitude +11.5 traveling fast across the constellations Pictor and Puppis.

    This is yet another example of how vulnerable we are to NEO's. Granted, a house size boulder is not of doomsday proportions, but, still extremely dangerous. According to http://janus.astro.umd.edu/astro/impact/ an asteroid this size would pack the punch of a half megaton nuke, and can be expected to happen about every 20 years. The NEO program operated by JPL is intended to catalog bodies in the 1 kilometer class, so it offers no protection from mere house sized bodies. The potential hazardous asteroid catalog by NASA accounts for about 1500 objects, the vast majority of which are over 150 meters in size. More modest sized rocks are not catalogued because they are too small to be detected. A 150 meter rock would be equivalent to a 200 megaton nuke and trigger a magnitude 7 earthquake. Pretty scary stuff.
