(meteorobs) Correction to previous Trig.calculation.

[stange34 at sbcglobal.net]

Agreed(in part) Chris.  It did lose mass by fragmentation earlier. But the 
possibility of that event being cited in the future as a classic earth 
grazer example is overwhelming to me and I await formal calculations by 
others that could substantiate that with bated breath. :-)
