[meteorite-list] Meteorite Times Magazine May Issue Now Up
Hello Everyone, As we get ready to celebrate this Memorial Day, let us not forget those whom we celebrate this day for and also for the heroes around us and in our own meteorite community. Please be sure to read Bob's article, 'The 2017 Veterans Meteorite Hunt'. http://www.meteorite-times.com/2017/5/ As always, a huge thank you to all our contributors. We appreciate all you do! Enjoy!

[meteorite-list] Oudiyat Sbaa, EH5 fall is now official.
Oudiyat Sbaa meteorite fall is official. This EH5 chondrite fell over Morocco on November 16, 2016. Oudiyat Sbaa25.546°N, 12.418°W Western Sahara/Morocco Confirmed fall: 2016 Nov 18 Classification: Enstatite chondrite (EH5) History: On November 18, 2016, at 4:40 pm local time, a bright fireball was witnessed traveling in a southerly direction by many observers in Morocco over an area extending from Tiznit to Guelmim, Tan Tan and Smara. Sonic booms were heard by Mbarek Bouilid, Aitoussi Redwan and three camel shepherds of the Aitboussoula family (who thought that perhaps the sound was caused by explosion of a mine trodden on by a camel). A search for fallen stones was begun, and on November 23 another shepherd (Bachir Alamine) found three black fusion-crusted stones on light brown sandy soil near Oudiyat Sbaa. Physical characteristics: The stones are completely coated in thin, black fusion crust. The fresh interiors are overall medium gray in color with abundant shiny grains of metal and sulfides. When first found the stones emitted a sulfurous odor. Petrography: (A. Irving and S. Kuehner, UWS) Some well-formed chondrules (apparent diameter 300±100 μm) are present within a recrystallized matrix containing abundant metal and sulfides. Apart from dominant enstatite, the specimen contains alkali feldspar, Si-bearing kamacite, niningerite, oldhamite, Cr-bearing troilite and schreibersite. A spherical crystalline object (apparent diameter 1.1 mm) observed in one thin section is composed predominantly of fluororichterite associated with a silica polymorph, enstatite and sulfides. Geochemistry: Enstatite (Fs0.4-0.6Wo0.1-0.3, N = 3), alkali feldspar (Ab88.7-93.1An1.1-0.9Or10.2-6.0, N = 2), metal (Ni 6.2-6.3 wt.%, Co 0.4 wt.%, Si 3.3 wt.%, N = 2). Cosmogenic radionuclides: (Å. Rosén, UBE/NMBE, GeMSE): Gamma-spectroscopy performed in February 2017 showed the presence of the following cosmogenic radionuclides: 46Sc, 56Co, 54Mn, 58Co, 7Be, 48V, 51Cr, 57Co, 22Na, 44Ti and 26Al. Recalculated to 18 November 2016 and assuming average EH chondrite density and composition, 48V was 43.0 (+7.8,-5.2), 22Na was 60.8 (+8.1,-4.6) dpm/kg and 26Al 53.6 (+7.9,-3.4) dpm/kg. The 22Na/26Al activity ratio of 1.1 (+0.2,-0.1) and detected activity of 48V (t1/2=16 d) are consistent with a fall in November 2016. Magnetic susceptibility log χ (× 10-9 m3/kg) = 5.74. Classification: Enstatite chondrite (EH5). Specimens: 173.7 g including one polished thin section and a polished thick section at UWB; 17.3 g plus one polished thin section at NMBE; remainder with DPitt.
