Hi All,

I'm sure Sterling is well aware of this, but it's worth pointing
out to the masses that 2011 MD wasn't "late". People are simply guilty
of blindly believing their favorite piece of software, apparently
ignorant of the limitations of non-integrating propagation. When an
asteroid is well within the sphere of influence of the earth, it is
hardly appropriate to use a program that's based on Kepler's two-body
equations... --Rob

The pass was at 7600 miles (instead of the
predicted 7500 miles) and it was 3.5 hours
late from the predicted time.

Mr. Newton could not be reached for comment.
