[meteorite-list] Lookout Tucson -- Anne Black is on her way
Hello and good day, Anne Black is on her way. I helped Anne load up her inventory for the show this morning. She needed to get a bigger vehicle this year to carry all her stuff. What a joy seeing just a few of the items she is taking to Tucson. I actually got to see and hold the Sikhote-Alin "tree section" she will have in her room. She also has quite a few books. Please buy them so I don't have to unload them when she gets back to Denver, Colorado. As most of you know, she shares a room with Geoff N. at the old Inns Suite. I sure wish I could see it this year. I'll bet it will be better then ever. Have a great show.

Re: [meteorite-list] report of the Geislingen (Germany) meteorite hunt
Great report Rob! Thanks for sharing. It's funny how we are all the same, the group picture could've been taken about anywhere in the world and who would know the difference. I think it's a blast when you finally get to meet people you've got so much in common with and actually get out and hunt. Too bad you guys didn't find any. I wouldn't give up just yet, they could be lying just over the next hill, or the next one, or.. Have Fun and Happy Hunting!

Re: [meteorite-list] MORE on ABSENTEE BIDS
Hello, Anyone intending to make an absentee bid: I will take absentee bids on the phone up to the day BEFORE the auction, BUT, to avoid confusion and be sure Your bid is placed, it is MUCH better if you get your bid Into me by email BY WED (2 days) this week. (That way You know your bid will be written into the MASTER CATALOG I will use during the auction - things get very hectic once I Leave San Diego. (Hell, they're hectic NOW! - but at least I have all my material readily available to me) You should get a confirmation from me within 24 hrs (or your email got lost and you should email again) Thanks, Michael __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
Re: [meteorite-list] Tucson INFO
Hi everybody, This has come up more than once, so, PLEASE READ: If you have been asked by a friend to bid FOR THEM, There are two possibilities which require completely different procedures: 1) You bid for them on your number and you PAY for the item(s) And you TAKE the items with you. This is no problem and Requires no action different than your usual bidding practices. 2) You want THEM to pay and me to ship to them - THEY must Email me, "register" as an absentee bidder. If you bid for someone Else either you pay or they have made arrangements with me In advance. - definitely pick up a bid card FOR THEM if they are Registered with me. Have them make it clear to me YOU will be bidding for them, NOT me! (It would not do for me to bid for them - you bid for them and they are driving up their own price!)

It was actually just a case of dumb luck that the radar got it at such a high altitude. Think of it like a baseball hitter holding his bat out and spinning in circles; when the pitcher throws the ball, the odds of the hitter being phased exactly right to hit it are very low. However, once the meteoroid breaks up into hundreds or thousands of individuals, the odds improve dramatically that the radar beam will intersect some of the meteoroid fragments when it sweeps through. > This leaves me to wonder how 15.69 degrees was chosen. Were all the > elevation angles checked or was it because of witness statements??? All elevation angles are manually checked for every radar and time that is reasonably close to that of the fall time. Meteorites can take up to 10 minutes to fall (though usually much less), so that provides guidance on how many images to sift through. --Rob __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] Looking for troilite nodules
Hello, I am a grad student doing a research project on sulfides in iron meteorites. I am looking for some very reasonably priced samples containing pristine troilite nodules in irons type IIIAB, IIAB and IVAB. I don’t need a lot of material, typically a few grams would be plenty, but that would be even better to have the nodules still embedded in the Fe-Ni alloy. The sample does not need to be polished and/or etched. Due to the nature of the project, I would prefer to buy from IMCA certified sellers. Please send offers off the list. Thanks!

Re: [meteorite-list] How to compute NEXRAD radar hit times
Marc, Rob! I found my error. However, when I originally tried this about a month ago, I could not duplicate 03:02:31. This was the biggest issue. I did not capture this so I do not know why. Maybe I was using level III. In any case, I was not changing the radial properties and I did not catch that. When I fired it up this morning, I was actually getting a radial properties pop-up screen, which I did not get before. That brought my attention to it and the default is very low...in the decimals. So I selected 15.69 and loaded that and there it was!! It is the only angle that shows it. I tried the 12 and 19 degree cuts to see. So, that issue is solved and thanks to you and Rob for your assistance. I was totally successful this morning with the entire process. This leaves me to wonder how 15.69 degrees was chosen. Were all the elevation angles checked or was it because of witness statements??? The Google maps tie in is a good idea. Every in regards to overlays is pretty much there. It would be nice to have two features added or changed. Coordinates with the ability to match the most common standards, selectable. DD., DD_MM.mmm, DD_MM_SS ( datum selectable too) and then the ability to move the map by inputting coordinates. Also, the program appears to default to the +Zoom value, I would suggest it be defaulted to just the movement of the map.
