I suggest the media is responding correctly for a change, by withholding the information until they can make a clear report. Otherwise the media would be creating real damage by getting people worked up, which could potentially be more damaging than the object itself even if it hit. The media creates enough damage in our world as it is already - lets not push them to do more.

SPACE WEATHER - 11/15/07
Something strange is happening in the atmosphere above Africa and researchers have converged on Addis Ababa, Ethiopia, to discuss the phenomenon. Scientists are converging on Ethiopia this week to discuss a new and strange form of space weather: ion plumes, which form during geomagnetic storms. Remarkably, the source of these plumes may be somewhere over Africa. "The plumes appear during geomagnetic storms and they can interfere with satellite transmissions, airline navigation and radio communications." Indeed, it is their effect on GPS signals that led to the discovery of plumes over North America just a few years ago.
Geomagnetic storms are major disturbances of the magnetosphere that occur when the interplanetary magnetic field turns southward and remains southward for an prolonged period of time. During a geomagnetic storm's main phase, which can last as long as two to two and a half days in the case of a severe storm, charged particles in the near-Earth plasma sheet are energized and injected deeper into the inner magnetosphere, producing the storm-time ring current.

I looked again at the Earth MOID (Minimum Orbit Intersect Distance). and still found it to be .0012501AU. An AU is apx 150,000,000 Kilometers. So I did the math: 150,000,000 X .0012501 = 187585 Kilometers
That is 187,585 Klm at it's closest approach to Earth as it intersects with our orbit. The moon is 384,000 Klm from the Earth.

Explain again just exactly how do you, or NASA, cover up an asteroid hitting Earth. I think someone would see it.

This is a LOT closer than the 500,000 kms MOID I last saw iirc. What I'd like to know is if MOID is our orbit PATH or Earth's actual LOCATION on that path, as the 2 are quite different things.

...
MOID is the point where the asteroid passes across the orbital path of Earth at it's closest approach to earth. Another asteriod could cross the orbital path 4 AU away from the earth so it's MOID would be 4 UA.
