Hello List,

The above link is a detailed map image which depicts
the ground path of the Genesis daytime fireball.

If any of you are lucky enough to witness this event,
and are interested in participating in a little
experiment, please contact me off-List.
The experiment is a test of our observational skills.
A sort-of "ground-truth" exercise.

Your participation in this experiment only requires
you to observe and record (to the best of your
abilities) the fireball produced by the reentry of the
Genesis bolide/spacecraft. Then contact me with your
results. (All-Sky Camera Networks are definitely to be
included in this effort.)

The intent of this exercise is to treat this recorded
data as if it were taken from observations of a "real"
(meteoroid) fireball. From this observational data we
will then "predict" a most likely fall location for
this "object". And finally, we will then look to see
how close that location compares to where Genesis
would have landed (had it no drag-shute or parasail).


The purpose of this exercise is to determine what
degree of accuracy can be expected from solely using
eye-witness interviews to determine a meteorite fall
location. It is hoped that these results will
develope some degree of confidence in the ability to
recover meteorites by this "eye-witness account"
method.

Should the "eye-witness" method fail, then the focus
shifts to determining the degree of accuracy by means
of the "All-Sky Camera" network, and to determining
what degree of confidence we can place in the ability
to recover meteorites with just a limited number of
cameras.

Would be interested in hearing your comments and
observations.
Bob V.

On September 8th, a daylight fireball will streak
across the western United States. It's Genesis,
returning samples of the Sun to Earth.
