Yafa .......................................1342'40" N, 4510'12" E
Yafa province, Yemen
Fell 2000 July 15, 14:45 h GMT
Ordinary chondrite (H5)
A main mass of ~5 kg and a second mass of ~700 g are known.
Many witnesses reported a fireball over a wide area from Ma'raban
to Aden (some 95 km to the south-southwest) to Ad Dhala (70 km
west-southwest of Ma'raban) and many in the region reported
associated sound effects.  The larger stone was collected on the day
of the fall, probably within 2.3 h of the event.  The smaller stone
was collected the following day.  Classification and analysis (G. C.
Wilson, UToron):  Macroscopically, the fall is a breccia, with well-
developed fusion crust and a pale interior.  Olivine, Fa19.4; ortho-
pyroxene, En81.3Fs17.3Wo1.4; kamacite, 0.56 wt% Co and 6.78 wt%
Ni.  Tetrataenite, averaging 50.3 wt% Ni, is an accessory mineral.
Shock stage, S2; negligible degree of weathering, consistent with recent
fall.  See also Wilson and Rucklidge (2001).  Specimens:  type specimen,
600 g, Yemen; 93 g and polished thin section, GSC; main mass believed
to reside with the finders (as of 2001 September 28).
