History: On 26 August 2018, a large fireball was widely seen and heard around the sparsely populated region of the southern area of the Jabal al Gharbi District of Libya. Hundreds of freshly fusion crusted stones, totaling over 100 kg, were found in early 2019, scattered over several kilometers, about 95 km southwest of Ash Shuwayrif by Mr. Belal. S. Omar Aliby (and other meteorite hunters) who visited the site. The fusion crust is fresh and matte black and lacks evidence of extensive wind abrasion. Given the complete lack of weathering of the stones, it is possible that they originated from the 2018 meteor seen in this region. In 2019, Mr. Marcin Cimala purchased 30 kg of the material from a meteorite dealer based in Mauretania. Stones of this possible fall are currently being traded under the name of Ghadamis. Physical characteristics: Many individuals from about 100 g to several kg, most unbroken stones are covered by matte black fusion crust. Many stones show well-developed shallow regmaglypts. Overall, the stones are blocky. Where fusion crust is lacking, the meteorite shows a light grayish interior. Specimen are very fresh; some show very minor brownish staining of exposed metal. Petrography: (A. Greshake, MNB; L. Garvie, ASU) The meteorite displays a recrystallized texture predominantly composed of compositionally equilibrated olivine and low-Ca pyroxene grains in some regions showing 120-degree triple junctions. Few flattened and delineated PO, BO (to 1 mm), and relict PP chondrules are present. Matrix contains plagioclase, chromite, merrillite, troilite, taenite, and kamacite. The plagioclase grain size is about 60 µm. Shock melt veins are rare, but pockets are locally present. Fe-Ni metal and troilite uniformly distributed across the polished section. Largest Fe-Ni grain ~1 mm across. Most kamacite grains are polycrystalline and contains finely dispersed sub-micron-sized troilite. Some show a complex metal-sulfide eutectic intergrowth. A few larger kamacite grains show a frosty etch and weakly developed Neumann bands. Troilite, to 0.5 mm across, is highly shocked, polycrystalline, and has a dusty appearance. Cu metal was searched for but not found. Geochemistry: (A. Greshake, MNB) olivine: Fa23.8±0.3 (Fa23.1-24.2, n=12), low-Ca-pyroxene: Fs20.2±0.3Wo1.6±0.2 (Fs19.7-20.9Wo1.2-2.0, n=12), feldspar: An11.2±0.7Ab84.4±1.1Or4.4±0.6 (An10.7-12.4Ab82.8-85.4Or3.7-5.3, n=4) Classification: Ordinary chondrite L6, S5, W0 Specimens: 200 g at MNB and 325 g at ASU.

History: On April 9, 2009, a bright fireball appeared over Carinthia and the Karavanke Mountains. The meteoroid entered the atmosphere at a steep angle and disintegrated into a large number of fragments after more than 4 s of flight. In Jesenice and its vicinity, witnesses reported loud explosions following the disappearance of the fireball. Eyewitness reports were documented and evaluated by Thomas Grau (ERFM, Bernau). Two Czech automated fireball stations of the European Fireball Network (EN) recorded the bolide. Based on photographic and photoelectric records taken by the stations, Pavel Spurný and Jiří Borovička (Academy of Science, Czech Republic) determined the atmospheric trajectory and heliocentric orbit of the initial meteoroid. The bolide was also recorded by all-sky and meteor cameras in Slovenia. The supersonic boom was registered by infrasound stations and seismometers in Slovenia, Austria, Germany, and Italy. The first fragment (2.35 kg) of this fall was recovered by Jožef Pretnar and Bojana Krajnc on May 17, 2009. A second complete individual of 361 g was found on July 21, 2009 by Ralph Sporn and Martin Neuhofer (46°25.079'N, 14°03.193'E) and a third one of 956 g by Danijel Repe on August 27, 2009 (46°25.473'N, 14°02.621'E). Total weight: approximately 3.667 kg. Petrography and mineral compositions (A. Bischoff, IfP; Miha Jeršek, SMNH): The rock is fine-grained and shows brownish taints (weathering) on surfaces of the broken pieces. Shock veins were detected. In thin section Jesenice is highly recrystallized and a few relic chondrules are visible indicating it is a type 6 chondrite. This is also supported by the large grain size of plagioclase and homogeneous olivine and pyroxene. Mean olivine and low-Ca pyroxene are Fa25 and Fs21, respectively. Classification: Jesenice is an L6, S3 ordinary chondrite. Specimens: Main mass and type specimens located at SMNH.
