Bernd replied: "Pribram's slope was given as 43� and the first observations of the Bavarian fireball (Neuschwanstein) gave a slope of 49.5�" Interesting that Neuschwanstein's (and Pribram's) entry slopes were so high. So I was right on Tagish Lake, wrong on Neuschwanstein. Come on Peekskill! Help get my guess accuracy back to 2 out of 3! ;-) Cheers, Rob P.S. I wonder how many falls have good estimates on their entry slopes. It would be interesting to see how mass and composition vary with angle. I would expect the higher angles to be dominated by irons or high-mass chondrites. Similarly, I would think the more fragile meteorites (e.g. carbonaceous chondrites, friable ordinary chondrites) would be more likely to survive only at shallow entry slopes. Tagish Lake supports this idea; how about Allende, or Murchison (whose strewn field covers some 33 km^2)? And for friable meteorites, how about Saratov or Bjurb�le? (Of course, the Bjurb�le and Saratov TKW's are both fairly large -- some 330 kilos each -- so they might have had a better chance of surviving steep entry angles). ______________________________________________ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list
