Bernd, Gaham;

About this new CR strewnfield, Dean Bessey had published the coordinates
recently, as follows. I transmit this info that I picked up on his website.
www.meteoriteshop.com if my memory is good.

Moroccan CR2 Strewnfield.

N 30 19 53 4

W 5 52 50 7

If it can help.

best wishes

Michel
