Gao-Guenie

A bit of news from the Meteorite Nomenclature Committee meeting in
Dublin, Jul 27, 1998:

Gao-Guenie, new name.	
	With the recent paper by Bourot-Denise et al. (1998), the Meteorite 
Nomenclature Committee has decided that a new, collective name, Gao-Guenie, 
will be bestowed upon all meteorites formerly identified as either "Gao 
(Upper Volta)" (frequently truncated to "Gao") or "Guenie."  It had been 
reported that two meteorite showers occurred one month apart in 1960 in 
the country now known as Burkina Faso. But, the new work confirms long-
held suspicions that the two meteorites are indistinguishable from each 
other, and that there was most likely only one fall (March 5, 1960).  The 
confusion about this meteorite has been compounded by the fact that new 
stones continue to be found almost 40 years after the fall, and are given 
arbitrarily one or the other name.  Henceforth, the official name for all 
meteorites from this shower will be Gao-Guenie, with the names "Gao (Upper 
Volta)" and "Guenie" as recognized synonyms.
