Many of these have something new I have never seen before. There is a "~" (tilde) in the type. For example - Acfer 393 (H~6) - obvious this means the petrologic type is "approximately" 6, but how/why is this being used in the nomenclature? Were stones like this ambiguous in some way and the exact type could not be determined? Or, is this some new naming convention we will see more of? Here is a link to the new meteorites - http://www.lpi.usra.edu/meteor/metbull.php?sea=%2A&sfor=names&ants=&falls=&valids=&stype=contains&lrec=50&map=ge&browse=&country=All&srt=name&categ=All&mblist=All&rect=&phot=&snew=2&pnt=Normal%20table&dr=&page=0 All of them, except for two, have this tilde in the type.
