Hi Jay and List,

This information is now a bit out of date. It was later determined (by
Sandia?) that
these were two distinct meteoroids. Neither the bolide observed over
Arizona/
New Mexico, nor the one seen from southern California produced a recovered
meteorite. When the two events were thought to be the same object, the
inferred trajectory placed the probable reentry point to the northeast of
Little
Lake (just off I-395, south of Lone Pine), and likely within the China Lake
military area. However, once the California event is disassociated from the
earlier AZ/NM earth-grazer, knowledge of the CA trajectory is inadequate for
potential recovery purposes.

Best,
Rob
