(meteorobs) Finding Meteorites From Observations

[Chris Peterson]

During dark flight the meteorite is traveling with the Earth. There is 
minimal displacement due to the Earth's rotation. The meteorite is just a 
falling stone. Any displacement due to Coriolis effects will be very small.

Subject: (meteorobs) Finding Meteorites From Observations


I'm not seeing any adjustments in the search areas for the rotation of the
Earth. It is significant, 457 meters per second (1500 feet) at the equator
and zero at the poles. I'm not an expert but the direction of the meteor to
the north/south axes, the latitude and the last point the meteor seen have
to be considered. I believe I've read that the dark flight lasts about 120
seconds. At the equator that would put the impact zone 55 km or 34 miles
from the expected point of impact. Impact tables should be caculated for
various angles and latitudes for meteorobs by those capable, then maybe
some meteorites could then be found from observations.
