Meteorite Times Magazine Meteorites and Telescopes by Jim Tobin
If you go back through this featureâ€™s back issues you will see that Paul and I have linked telescopes and meteorites together in many and interesting ways for years. We were regular sellers at RTMC the premiere amateur astronomy gathering in So Cal. We always have one with us for after meteorite hunting star gazing. So mix an opportunity to see telescopes, Geoff Nokin and the Aerolite Meteorite team in our area and we are there. Great weather, and easy traffic made for a nice two hour drive putting my wife and I down at Oceanside California for the 8th Annual Southern California Astronomy Exposition. Geoff was to speak to the gathered crowd at 4 pm but we wanted to get there way before that to visit with him if we could and to look around at the booths of telescope and imaging equipment. It was also an opportunity to get a copy of Geoffâ€™s new book, a wonderful biography of his life with rock and roll and rocks from space. Paul and Janice were going down separately and we would meet up with them there.
Paul and Janice (partly hidden) talking to the Aerolite Meteorite team while Geoff poses for a photo with a fan. When we arrived Geoff was signing autographs and posing for pictures with a troop of scouts. He was clearly having fun already. We got a chance after a while to talk for a couple minutes and greet his team. Sara found a Sikhote Alin pendant that she liked and I fell in love with the Admire acrylic displays and got one of those. Paul like them too and got one. They will go so well with the Brenham ones we got a few years ago. A perfect way to display the Kansas pallasites side by side.
The test of strength for many a man and boy that day was the brief lifting of this nicely sculpted iron weighing in at over 40 kilos.
What a beautiful Fukang pallasite slice, I had to get a picture with some light behind it. As much as I would like to stand there and talk to Geoff for a long time he is out to do business so we let him work. At that point it was just fun to stand back and hear the story of meteorites told repeatedly to the eager listeners by one of the worldâ€™s master meteorite story tellers. I remember sitting in the sun at RTMC and telling the story of tektites to hundreds of eager knowledge seekers over the years and so does Paul. I think we both got a kick out of seeing Geoff at work.
I love everything about etched irons, but this one happens to be cut with the orientation to the internal structure that I love most. I just find the triangle Widmanstatten pattern the coolest.
Some of the trays and cases of meteorites that were brought for the space rock fans to enjoy and buy from. We had walked around the parking area where the booths were set up and I had taken some photos. It was just enough cloudy to prevent the use of the solar filtered telescopes. They are always one of my favorite scopes to look through. I try to sneak a couple photos afocally with my camera if there are any cool prominences showing on the Sun. Early on I had been introduced to David Ho of Hotech who is a friendly enthusiastic gentleman. He is the creator of the really neat combination laser pointer, red flashlight and white light unit that we saw Geoff use in the Meteorite Men TV series. Geoff has carried and enjoyed the product for quite a while. I was given a sample to test and the following is the product review. I do not do these or book reviews anymore except on rare occasions. This is a very cool device. Its sturdy, powerful, designed to carry and use easily. For those of us who have been stuck in the desert and who go to places out of touch with the rest of the world emergency signalling tools are a necessary requirement. I have a antique brass magnetic compass and an antique British police whistle attached to my hunting backpack whenever we go out. Using either its clip on holder or belt looped plushy fabric case Davidâ€™s green laser and flashlight combo makes a great addition to the hunting kit. Its in mine from now on. You just never know when something bad might happen and as a scout â€œBe
Prepared” is always in the back of my mind. The Astro Aimer as it is called is threaded on the side so it can be attached to a photographic tripod or mounted on a telescope. It also comes with a lanyard so you can wear it. One of my all time biggest problems as an amateur astronomer has always been finding my red light, night-vision protecting flashlight. And then there are the times when you go inside your blacked out vehicle and need a white light to find something in there. So you have to struggle with finding the regular flashlight you did not think you would need. Now with the advent of green laser pointing aids to show people where the telescope is directed or where an object is in the sky you need to carry one of those around with you too. HoTech has put all of this in one package that is really nice. The powerful little green laser is on a timer so it turns off automatically after 50 seconds and you don’t have to hold a button down after you turn it on. The red LED has three brightness settings and the white LED is true white and bright enough for many normal tasks. Hotechs’s contact information follows for anyone wanting more information.
Astro Aimer G3 with belt clip, lanyard, and fabric case. As the picture shows you can find out everything you need to know at HoTechUSA.com Four o’clock came around and chairs were set up in one of the areas that only moments before had been a wandering zone in the center of surrounding booths. Geoff took the stage and gave a great presentation full of facts and information, readings from his new book and humorous tells of his meteorite hunting. He took some questions from the audience which were answered with more wonderful stories of adventures chasing extraterrestrial treasure. We had our drive back to look forward to and wanted to get some dinner so not too long after he finished his talk we made our way over so say goodbye. We had hoped that Geoff’s schedule would allow him to dine with us but alas that was not to be. So the four of
schedule would allow him to dine with us but alas that was not to be. So the four of us headed off to get something to eat and have some more fun. What a great day spent with friends. Oh, and the meteorites, and scopes were pretty nice too.
Just one more parting shot of Geoff as he answers the question from a very well spoken young man in the audience. Post script. The impact melt breccia that I found at Tucson this past February has received a name (NWA 7347) and is in the system waiting approval by the Nomenclature Committee. Until next month enjoy, Jim

Meteorite Times Magazine Holbrook – 100th Anniversary (2012) – Meteorite Hunt by Robert Verish Images from the gathering of meteorite hunters celebrating the 100th Anniversary of the Holbrook Meteorite fall. Sixteen (16) meteorite hunters showed-up in the Holbrook strewn-field at the very moment – when the fall had occurred – exactly 100 years later. Even though the 100th Anniversary day, July 19th 2012, came on a Thursday this year, there was still a good turn-out of meteorite-hunters for a middle of the week Group Hunt. This Holbrook 100th (Anniversary) Hunt was going to be a three-day event that would carry-over into the weekend, and indeed, more people did show-up on Friday night and Saturday, but the attraction of finding a Holbrook meteorite on this day, the 100th Anniversary of this classic Arizona fall, is what made for this good Thursday turn-out.
(From left-to-right: Richard Garcia (his camera took this picture), Jason Snyder Jim Wooddell (with best-friend, Franny), Wendy Wooddell, K.G. Bowling (Mark’s father), Mark Bowling, Don Morin, Twink Monrad, Troy Ball, James St John, Jim “Bones” Shorten, Ron Golden (Paula’s brother), Paula Lake, Gregg Lake (Paula’s husband), Bob Verish, Kat Cole (Twink’s niece). http://firstname.lastname@example.org/msg105275.html On Thursday, didn’t arrive at Holbrook until late afternoon. Checked-in at the Motel 6 before heading-out to the strewn-field. While checking-in we met a lot of people that
had been hunting that day and were now taking a break from the heat before going back out to the field. The good news was that most everybody had already made a couple finds. Dropped-off my bags in my room, put on my hiking boots, and grabbed my water bottles even though the sun was setting. Storm clouds started to form out on the horizon, but they never threatened, yet they gave some hope for shade. It seemed that everyone was heading back out to the strewn-field at the same time. In the last few remaining hours of daylight, I managed to find two small, sub-gram Holbrook individuals. As the sun touched the horizon, we all knew that it was time to take the group picture. Setting-up all of the cameras made for a very curious scene. Synchronizing all of the time-delayed cameras and having all of the cameramen run back (at the same time) to get into the picture was humorous and made it easy for everyone to be smiling. This feat required a couple repeat takes. But the exact moment finally came, and on this take, everything “clicked” – the clouds parted, the setting sun came out, the train came by, and a hundred years came and went since first the Holbrook Meteorite fell. Eventually it became too dark to search the strewn-field any longer and we all metup back in town. Unlike last year, where there would be a speaker leading various group-activities in the central courtyard of the Motel 6 each evening, this year everyone would just show-up with food and drinks, and we just partied. Of course, most of the conversations were about meteorite-hunting. And although there was no one expert leading a classroom-like discussion, there was still a lot of expertise that was shared between the more-successful Holbrook-hunters and the lessexperienced students. Several people remarked that these conversations made a marked improvement in their meteorite-recovery over the course of the weekend.
Above are the 9 Holbrook finds that the Wooddell’s made on Thursday, the 100th Anniversary date (2012-07-19). (Image courtesy of Jim Wooddell©2012.)
A lot of people told me that, if I go to Holbrook this year, not to expect to find very many meteorites, especially not after the highly successful group hunt at the “99th Anniversary” gathering where over 100 people found 93 fragments of the Holbrook fall. I may have even bought into that kind of thinking, because I remember saying, “Yeah, maybe. But I’m going anyway just to socialize.” Which ended-up being true, because even if I hadn’t found any meteorites, I can honestly say that I still would have had a great time meeting and hunting with everyone, and then at night just hanging-out with everyone at dinner and at the motel, and just talking “meteorites” all night. As it turned-out, the Holbrook finds were the “icing” to the literal icing of Twink’s delicious Holbrook Cake, which we all shared.
Twink Monrad (famous for her “Gold Basin Cakes”) baked a big Holbrook cake. It was really big, so there was plenty for everyone. (Image courtesy of Twink Monrad©2012.) That’s not to say that my scientific-curiosity wasn’t piqued as to whether or not the surface of the Holbrook strewn-field could “bounce-back” and offer-up more Holbrook stones in time for the 100th Anniversary gathering. This was of enough interest to me that I wanted to be there and witness first-hand the out-come of this group hunt. (As it turns-out, the Fislers have done a good job of documenting their return visits to Holbrook which shows that this “bounce-back” interval of time is probably much shorter than would be expected.)
The “South-side” (a view to the south from the train tracks). (Image courtesy of Mike Mulgrew©2012.) Compared to last year, there were fewer people hunting the strewn-field (based on a per-day total) this anniversary. And there were fewer first-time hunters this year. Although there were fewer people making their “first-time finds” this year, there were a total of 93 Holbrook meteorite finds reported this weekend, which is remarkable, since that was the exact same number that was reported last Anniversary! And although the total reported weight for the weekend was half of what was reported last year, it must be kept in mind that there was one monster stone found during last years Anniversary Hunt that weighed 240grams, and if you subtract that from last years total, the two Anniversary totals are remarkably comparable. So if anything, this shows that the group this year was more productive than the group last year. Want to see more “numbers”? On the DesertSunBurn YahooGroup website, there is a compilation of these finds listed in a file titled, “Holbrook 2012 REVISION 4.xls“. So, in a nutshell, here are the totals: At least 22 meteorite-hunters found 93 meteorites (not aware of any first-ever finds) over a 3-day period (July 19-21, 2012) totaling over 200grams. I had more images that I took of the Holbrook 100th Hunt, but I lost those that were in one of my field cameras that just simply died. So, I want to say “Thank you!” to all of you who gave me permission to use your photos. To wrap-up my report I would like to end with a Photo Gallery of in-situ images of my finds:
My 1st find made on the 100th Anniversary date, 2012 July 19th. (Found an hour after my arrival in the strewn-field.)
My 2nd find made on the 100th Anniversary date, 2012 July 19th. (Found within an hour of recovering the first find.)
My 2nd find was found exposed right on the edge of a weathered hoof-print. Rainwater washing the silt back into the hoof-print has exposed this once buried stone.
My 3rd find for the weekend was found exposed right at the base of an eroded hummock.
Because the shrub that once protected it, is now just a stump.
My 4th find was found right out in the open on a bare, smooth mudflat. (Right where I was told “You won’t find any on those surfaces”.)
My 5th find was found with a magnet-stick near an old, eroded ant-hill. (At 0.06grams, it’s rather heavy for it to be an ant-carried stony. Would be equivalent to me carrying the Old Woman Meteorite on my shoulders back to my garage!) The ant-hill grains of sand that are attracted to a magnet need to be examined under a microscope in order for them to be identified as meteorites. Fortunately, these “micro-meteorites” often look just like their bigger brothers, especially if they are 100% fusion-crusted grains, but if they are fragments it could be difficult to get a convincing ID. Unfortunately, the train-tracks are underlain by a bed of “slag” which has spread throughout the strewn-field supplying some very convincing meteoritelooking sand grains.
On the south-side standing on a high dune looking toward the northwest in the morning. (A train is traveling west, up the strewn-field, going towards Holbrook.) I am looking forward to next year, and to the “101st Anniversary Holbrook Meteorite Hunt”.

Meteorite Times Magazine IMCA Insights – August 2012 by IMCA TEAM It is still very hot here but the Denver Show is just a few weeks away. Yes, it is this time of the year again, time for our Yearly Elections! And to make it absolutely sure that not one single member missed this opportunity to become a Director or to vote for their favorite candidates; we are devoting a whole issue of our newsletter to it. Additionally, this year we are going to ask a bit more of all of you, we are going to ask you for your opinion on a few changes we are considering, more about that very soon on the IMCA mailing list, but we believe you will be interested so make sure you are getting your mail. And since you must be a Member in good standing to vote, this might be a good time to check on that, do we have your correct current email address? Did you pay your dues for 2012? If you are not sure, this would be a good time to check by asking the Board (email@example.com). What’s next? In accordance with our ByLaws, three Board Members will be elected in 2012, and at least six Candidates will be up for election (our ByLaws require a minimum of two Candidates for each vacant Board position). Something that brings us to the first phase of our public elections: the Nominations. Nominations: Volunteers Wanted! The requirements to be a Candidate are very simple: you must have been a IMCA Member in good standing for at least two years. And since we are an International Association we really want the Board to be International too, so go ahead be a Candidate, even if your English is not perfect, If you have any questions regarding your Membership, this would be a good time to contact us, and to ask about your status. A great many of you do qualify. So tell us now that you want to participate in the shaping of our Association for the future. If you really must think about it first (or ask a few questions) we will give you until September 12, 2012, but we must have your email announcing your candidacy no later than September 12, 2012, midnight (Eastern Time). Remember – we need at least six Candidates as our Bylaws require two Candidates for each open slot on the Board. We’re just waiting for a sign from you! Contact the Nominations and Elections Committee at firstname.lastname@example.org to let us know that you want to be a Candidate for the Board of Directors. If you want to nominate someone else, that’s also fine with us – just make sure that the Nominee is aware of that nomination, and that he’s actually willing to accept it. In any case, we will have to receive a formal notice by the Nominee, stating that he accepts his nomination no later than September 12, 2012, midnight (Eastern Time).
FAQ: How much Work is it? We often have been asked how much work it is to serve on the IMCA Board of Directors. Is it time consuming? There’s no simple answer to that, and it certainly depends on if you are just serving as a Board Member, or as a Board Officer. Naturally, the Officers will have to invest a bit more time and energy into their respective tasks – but then, you won’t have to volunteer for an Officer’s position after the elections. In any case, be prepared to engage in a frequent discussion with the other Board Members, voting on Membership Applicants, resolving disputes, investigating complaints, etc. Besides that, you might be asked to serve on one of the Committees, such as the Nominations and Elections Committee, the Membership Committee, or the Website Committee. Of course, you will be a bit busier if you are a member of the Nominations and Elections Committee at this time of the year. Besides that, working on other Committees, such as the EoM Committee, can mean a lot of work: just ask Bob Falls who does a fantastic job answering your questions and constantly updating the IMCA Encyclopedia of Meteorites. Just have a look, and you will see what we mean. Thanks to Bob for all of their time, great work, and enthusiasm. The continuing work on the EoM, the open discussion of international meteorite laws, business practices, a major over-all of our website and other important issues will sure keep all new and old Directors busy, but don’t worry, we all have a life beyond IMCA and its Board of Directors, and we are all used to teamwork. Of course, we would prefer to see Candidates running that are more active Members, and who are actually willing to give their best for our Association. But then, we are fully aware of the natural restrictions put upon us by everyday life, and other commitments. So, What’s Next? After the nomination phase, which will end on September 12, 2012, midnight (Eastern Time), we will take a few days to verify the eligibility of all the Candidates, and we will publish the names of all the Candidates on September 15, 2012 via our IMCA Mailing List. The Candidates will then have a two weeks period (from September 15 to September 29, 2012, midnight, Eastern Time) to explain to the whole Membership why they want to be a Director, and to answer all your questions (again, via our IMCA Mailing List). And we will actually vote during the week of September 30 to October 07, 2012. Please have a look at our official Election Schedule for more information, and technical details. Official IMCA Election Schedule September 12 (midnight Eastern Time): Deadline for Nominations Contact the Nominations and Elections Committee to let us know that you want to
be a Candidate for the Board of Directors. (eligibility requirements – 2 years as a dues paying member in good standing) September 15: Publication of the List of Candidates September 15 – September 29 (midnight Eastern Time): Campaign The Candidates may tell the Members (via our IMCA Mailing List ONLY) why they want to sit on the Board of Directors, and answer other Member’s questions. Their statements and answers will be published to our entire Membership during that time (again, via our IMCA Mailing List ONLY). September 30 to October 07 (midnight Eastern Time): Election Week All members may vote for the three Directors only ONCE at any time during this period. And exceptionally, this year we will ask you to answer a few questions, more about that in the near future on the IMCA mailing list. Voting begins September 30 and ends midnight October 07 Eastern Time. The special voting email address will be published via the IMCA Mailing List. (If you are not on the IMCA Mailing List and wish to vote, contact the Nominations and Elections Committee). Please be sure to use the mailing address we have on file for you, so we may verify that the vote is coming from a registered, eligible Member. Please contact us if you have any questions. We’re looking forward to your participation, and to your votes. Thanks. Other Ways to Support the IMCA If you are not sure if you want to run for the IMCA Board of Directors, but willing to actively support the IMCA there are indeed other options, such as volunteering to help in one of our various Committees, or by answering some of the many questions which we receive via our Contact form. We would be very grateful for any kind of help you can offer, especially since the number of questions and requests has been exploding ever since the “Meteorite Men” have become popular through TV, and other media have focused on the subject. So if you are willing to help, contact us, or just drop us a line via our Contact form (email@example.com), and we will be in touch with you. Thanks. Best Regards to all of you! In the name of the IMCA Board of Directors, Jeff Kuyken, President IMCA Inc. Anne Black, Vice-President IMCA Inc.

Meteorite Times Magazine Javanite “Fire Pearls” by Norm Lehrman
Part of the Australasian tektite event, Javanites are characterized by deep intricate etching and a brilliant gloss. Known as “Agni Mani” in Sanskrit (roughly translated as “Fire Pearls”), the fabled Javan tektites have a rich cultural lore collected in an entertaining book by Latvian Baron Richard J.H. de Touche-Skadding. (Agni Mani: Magic Gem from the Moon: Ballantine, 1966; Mayflower 1968). While the book purports to be a non-fiction account of his 30-year search for the stones, it seems as highly embellished as the skin of a Javanite. None-the-less, Touche-Skadding was a believer and presented specimens to then-Princess Elizabeth, Winston Churchill, and Lord Louis Mountbatten in the 1940s with the hope of blessing them with the legendary good luck of the Agni Mani. (specimens from the author’s collection).
