Re: [meteorite-list] Met Bulletin Updates - 2 NWA's and a Nova, and a Question regarding Nomenclature
The way it works is that meteorites are named based on how much certainty we have about where they come from. When we think the coordinates are accurate, we can name them after very local features. For things like NWA and Sahara meteorites, we have some confidence that they come from northwest Africa and the Sahara in general, but not much more than that. The hallmark of the Nova series is that we don't have any good information about where they were found, or, in some of the early ones, we thought that information was false. Nova 011 simply turned up in a market in Russia.There is no accompanying find story. Perhaps it's from Russia, perhaps it's an NWA, who knows. If there was some kind of find story indicating a local origin, we might have named it differently, perhaps South Russia or something like that.

Re: [meteorite-list] Met Bulletin Updates - 2 NWA's and a Nova, and a Question regarding Nomenclature
Hi Mike and all! 3.4 Meteorites of unknown or poorly known provenance. (a) Withheld information. Where the source of a new meteorite cannot be determined due to the withholding of geographic information by a collector or other party, the name should be chosen to reflect the smallest geographic feature identifying the collection location with certainty. If the location information is too vague, or is uncertain or disputed, the name Nova followed by the next available three-digit number should be adopted as the permanent name. (b) Transported meteorites. When the provenance of a new meteorite cannot be determined due to a lack of sufficient historical information, it should be named after the locality where it was first recognized. For meteorites found in institutions such as universities and museums, the name may be either that of the institution, the collection, or the city in which the institution is located. In accordance with§3.6, the names of people, even if part of the official name of the collection, should be avoided. (c) Meteorites found in large numbers. In cases where many meteorites are found and distributed or sold without careful documentation of provenance, a numbered sequence of generic names should be used as in §3.3c, wherein the prefix reflects the geographic area in which the meteorites were most likely recovered (e.g., Northwest Africa, for meteorites coming from marketplaces in Morocco). That might help answer your questions. - Original Message - From: Michael Gilmer meteoritem...@gmail.com To: meteorite-list@meteoritecentral.com Sent: Friday, April 20, 2012 9:20 AM Subject: [meteorite-list] Met Bulletin Updates - 2 NWA's and a Nova,and a Question regarding Nomenclature Greetings Bulletin Geeks, There are 3 new approvals today.

Hi Jeff, should Paris then not rather have been named a Nova too than a Paris? (From the Bulletin Database: Paris Unknown location (..) History: This sample was in an auction box lot bought by Jean-Jacques Corré at the Hotel des Ventes in Paris. The box was part of the estate of Jean Simon Colonna-Cimera, an Ingénieur des Mines, who supervised mines in foreign countries and in the French Colonies. Corré thought that the stone might be a meteorite but kept it for 7 years before attempting to have it identified.
