History (P.-M. Pelé, meteor-center.com): On September 5, 1814 at 11:40 a.m., a meteorite shower fell on the town of Temple-sur-Lot, located about twenty km north of Agen, and in surrounding localities. Several reports were written and they related in some details the circumstances of the fall : a kind of cloud had appeared in the sky from which light streaks left. Then three or four explosions were heard followed by several others less violent, like a roll of thunder. The cloud having appeared to be divided into four or five parts, witnesses saw several large stones fall. Many stones likely fell but only four of those were well documented.

History: A bright fireball appeared over Aiquile, Cochabamba district of Bolivia, on 20 November 2016, 17:57 local time (UTC-4). Stones fell in a strewn field of at least 12 × 2 km (northeasterly direction) in the following Aiquile communities: Tablamayu, Panamá, Chawar Mayu, Chaqo K’asa, Barbechos and Cruz Loma. The main bolide fragmentation occurred over the Tablamayu community, 12 km north of Aiquile. In the Cruz Loma community, C. Veizaga witnessed the fall of the largest stone (36.3 kg) about 500 m from him. He recovered the stone and in the following day the local Aiquile government (Luiz L. Arnez, Marco Cardona, Franz Navia, William Rodriguez, Jesus Yave) took the stone to the city museum. In the Panamá community, Roberto Soto witnessed the fall and recovered two other fragments (565 g, 2.2 kg). SERGEOMIN (Miguel A. Muriel, G. Villca, A. Perez), UMSA (Gonzalo Pereira), Brazil NM collaborators (Andre R. Moutinho, José M. Monzon) and S. Medina found additional fragments in the Panamá community. A. Moutinho found a 98 g fragment which was used for classification. Physical characteristics: The 36.3 kg stone was almost fully covered with fusion crust and remaglypts, with only small pitted corners (47 × 17 × 26 cm); the 2.26 kg stone is semi-prismatic and almost fully covered with fusion crust; the 565 g piece is a fragment mostly without fusion crust. Petrography: Medium shock stage (S3), chondritic texture and mineralogy and mineral compositions of an equilibrated ordinary chondrite. Porphyritic olivine and radial pyroxene chondrules dominate. Geochemistry: Microprobe analyses show an equilibrated olivine and pyroxene composition of Olivine (Fa18.3±0.5; n=53), low-Ca pyroxene (Fs 15.7±0.7; n=37). Mean Cr2O3 of olivine is 0.048 wt.% for both matrix and clasts areas. Classification: H group classification based on: chondrule mean apparent diameter (~0.3 mm), content of metallic Fe,Ni + FeS (9.9 vol%), Co content of kamacite (0 - 0.3 wt%). Petrologic type 5 classification based on chondritic texture, and plagioclase

History (P.-M. Pelé, meteor-center.com): On July 24, 1790, around 9:30 p.m., Mr. De Carrit-Barbotan and Mr. Baudin were walking through the courtyard of the Castle of Mormès. They observed suddenly an intense glow. Raising their heads, they saw a fireball heading south to north, according to their report (although this trajectory is questionable). The meteor broke up into several glowing fragments. Three minutes later, a violent detonation was heard. The object fragmented near Julliac and a number of stones fell over a fairly large area. Stones fell in the moors, in the forests, in some farmyards, but without causing any known damage to houses; according to the Marquis de Drée, a stone might have killed a shepherd and cattle, but there is no proof. The phenomenon was observed as far away as Limoges. The strewnfield of the Barbotan meteorite fall is extensive, as it goes from Losse (Landes), Mézin (Lot-et-Garonne), Eauze (Gers) to Créon d'Armagnac (Landes), according to reports. It is impossible to know the total mass of this fall, but it is certainly more than 50 kg, and is probably close to 100 kg. Many stones weighed from 2 to 4 pounds (1 to 2 kilograms). Several stones weighed from 18 to 20 pounds (9 to 10 kg). The largest is said to have weighed 45 kg. Places with reported stones: Eauze: 43°51'44.17"N, 0° 6'1.28"E Cazaubon: 43°56'2.62"N, 0° 4'14.99"W Créon d’Armagnac: 43°59'40.08"N, 0° 6'20.33"W Mézin: 44° 3'22.29"N, 0°15'23.20"E Lagrange: 43°58'26.93"N, 0° 6'25.71"W Losse : 44° 6'35.42"N, 0° 6'12.04"W

History: A fireball was witnessed in the area, but no records of the direction of movement were recorded. A single stone of 3165 g was found by A. Salem El Moichine, a local resident, on the same day at 13:00 hr local time, 11 km SE of Bassikounou. The sample for classification was provided to NMBE by M. Ould Mounir, Nouakchott, who obtained it from his cousin who recovered the meteorite. According to S. Buhl (Hamburg, Germany), more than 20 specimens were later recovered by locals and meteorite finders. These finds define a 8 km long strewnfield. The total recovered mass is 46.00 kg. Physical characteristics: The 3165 g specimen is largely covered by black fusion crust. The interior is light gray. On the surface of the fusion crust there is some adherent soil material, some of which is bright red. Shortly after recovery, the stone was cut into two pieces of 1200 and 1950 g. The larger piece has a rectangular shape and shows indications of flow-lines in the fusion crust. Petrography: (E. Gnos, MHNGE; B. Hofmann, NMBE, M. Eggimann, Bern/NMBE): Mean chondrule size 0.35 mm (n=53). Metal abundance is 8 vol%, troilite 6.6 vol%. Mean plagioclase grain size is ~20 mm. Troilite is polycrystalline, rich in silicate inclusions, and shows diffuse boundaries to metal. Metal is partly rich in silicate- and troilite inclusions. Rare metallic Cu (10 mm) occurs at kamacite-taenite boundaries and in troilite. Some shock veins and no weathering products were observed. Mineral compositions: Olivine (Fa18.6), pyroxene (Fs16.3 Wo1.1), plagioclase (An13.7). Cosmogenic radionuclides: (P. Weber, PPGUN) Gamma-spectroscopy performed in December-January 2006 showed the presence of the following radionuclides: 48V, 46Sc, 56Co, 54Mn, 58Co, 7Be, 51Cr, 57Co, 22Na, 26Al and 60Co. Recalculated to 12 October 2006 22Na was 38.0±2.2 and 26Al 31.5±2.1 (both dpm/kg), the activity ratio of 1.21 is fully consistent with a fall on that date. Classification: Ordinary chondrite (H5); S2, W0. Type specimens: A total of 115 g are on deposit at NMBE. Boudreaux holds the main mass.

History: In fall and winter, 2007 ~100 kg of meteorites were collected in the Erg Chech, north of Taoudenni. Nomads reported the stones fell after a smoke cloud was seen and several detonations were heard over a wide area during daytime in July 2007. The finder of the first meteorites was Mr Ouled Bleila, who died in a car accident on his way back from the trip to the Chergach strewn field in October 2007. According to the Tuareg people from Algeria who visited the fall site in September 2007, the elliptical strewn field stretches for more than 20 km in a northeasterly direction. No fireball was reported. Physical characteristics: A large number of fusion-crusted stones have been recovered, the largest ones are 17.8 and 13.9 kg, the smallest ones about 1.5 g. Total known weight ~100 kg. Petrography: (E. Gnos, MHNGE; B. Hofmann, NMBE, M. Eggimann, UBE/NMBE) Mean chondrule size is 0.38 mm (n = 61). Mean size of plagioclase grains is ~20 μm. Troilite is polycrystalline, rich in silicate inclusions, and shows diffuse boundaries to metal. Some metal is rich in silicate- and troilite inclusions. No Cu metal observed. Shock stage is S3, some shock veins are visible, no weathering (W0). In addition to this dominant lithology, a significant number of stones consist of chondritic clasts (H5 S3-4 W0, identical to the homogeneous lithology) set in a fine-grained, black, silicate impact melt matrix with abundant droplets of metal and metal-troilite. Shock stage of small clasts is up to S4. Mineral compositions and geochemistry: Olivine Fa18.2 (chondrite fragments in impact melt are Fa18.4), pyroxene Fs15.5 Wo1.2 (fragments in impact melt are Fs16.0, Wo1.4). Cosmogenic radionuclides: (Patrick Weber, Particle Physics Group, Institute of Physics, University of Neuchâtel) Gamma-spectroscopy performed in November, 2007 showed the presence of the following short-lived radionuclides: 46Sc, 56Co, 54Mn, 58Co, 7Be, 57Co, 22Na, 60Co, 26Al. Recalculated to July, 2007, 22Na was 44.0 ± 1.1 dpm/kg and 26Al 20.8 ± 0.8 dpm/kg. The 22Na/26Al activity ratio of 2.1 is consistent with a fall in July, 2007 and demonstrates that this material is not identical with Bassikounou. Classification: Ordinary chondrite (H5), some stones suggest an H impact melt breccia. S3, W0. Type specimens and distribution: 115 g at NMBE; 17.8 kg P. Hermann, Canada; 13.9 kg D. Gheesling, USA; 4.9 kg S. Buhl, Germany.

History: On October 31, 2006 between 10 and 11 am, local time, a sonic boom and change in sky color frightened local residents in Adamawa State. Nigerian authorities were alerted and the incident was reported on Nigerian television. Three meteorite individuals totaling 4 to 5 kg were subsequently recovered in and around the village of Demsa. The reports came to the attention of meteorite hunter, E. Egbe of Kaduna, who traveled to the location and was able to purchase one crusted 980 g individual stone. This stone had been struck with a hammer, and the reassembled mass (consisting of five pieces totaling 959 g) was purchased by Twelker in April and July 2007. Physical characteristics: A single fresh, gray stone (959 g) with glossy black fusion crust. Petrography: (A. Irving and S. Kuehner, UWS) Fresh specimen containing sparse chondrules (mostly 0.7-1.4 mm, some up to 2.5 mm) in a coarse-grained matrix rich in holly-leaf shaped metal grains.The matrix plagioclase ranges in size from 100 to 300 μm, and accessory troilite and merrillite are present. Geochemistry: Olivine (Fa19.1-19.4, N = 3), orthopyroxene (Fs16.5-17.2Wo1.7-1.3, N = 4), clinopyroxene (Fs5.4-5.5Wo46.4-46.0, N = 2). Classification: Ordinary chondrite (H6). Specimens: 20.7 g of sample and one polished thin section are on deposit at UWB. The main mass is held by Twelker.

History: (H. Haack, NHMD): A bright fireball was observed over eastern Denmark Feb. 6, 2016, 22:07:19 (UTC+1). It was overcast in the area below the fireball, but many people reported having seen a very bright light. Pictures of the fireball were taken from three locations in Germany and one in Austria (at a distance of 890 km) by automatic cameras designed to take pictures of noctilucent clouds. A surveillance camera on the Danish west coast also recorded a video of the fireball. None of the cameras in the Danish fireball network had clear skies during the event. 279 reports with observations of the fireball and/or sound phenomena were received by the Danish fireball network. Loud sonic booms were heard by many people up to 30 km from the place where the meteorites were found. The day after the fireball was observed the first meteorite (60 g fragment) was found on the tiles in front of the main door of a private house in Ejby, which is a suburb in the western part of Copenhagen. The owner of the house had not seen the rock before. Later that day 6.5 kg of shattered fragments were found on the tiled courtyard of a business property. These fragments had not been there when the business closed on Friday – the day before the fall. During the following 19 days a total of 11 individual meteorites were found in an area measuring 5 × 5 km. The biggest piece weighed 6.5 kg. It hit a tiled area and shattered into hundreds of fragments. Physical characteristics: 11 meteorites have been recovered, with a total mass of 8938 g. Some of the fragments were recovered wet and the weights are therefore decreasing as the samples dry out. Petrography: (M. Patzek and A. Bischoff, IfP). Based on the study of the thin sections, Ejby is unbrecciated. Highly recrystallized areas with large plagioclase grains were observed, and areas with abundant relict chondrules also exist. Thus, the rock is transitional between type 5 and 6. In places, high metal and sulfide abundances were found. Olivine shows undulatory extinction indicating that the rock is very weakly shocked (S2). As opaque phases metals (kamacite, taenite), troilite, and chromite were observed. Other accessory phases include Cl-apatite and merrillite. Geochemistry: (M. Patzek and A. Bischoff, IfP). The mean composition of olivine is Fa19.3±0.1 with a compositional range of Fa18.8-19.5 (n=19). The low-Ca pyroxenes have a mean composition of Fs16.9±0.2 (n= 21), range Fs16.4-17.2. Mean plagioclase is An11.5±0.9Or6.0±1.6 (n= 10; range An9.0-12.8). Kamacite has mean Ni- and Co-concentrations of 6.3 and 0.45 wt%, respectively (n=8). The taenite composition has 48.7±2.8 wt% Ni (mean Co: ~0.05 wt%; n=10). Specimens: Except for a few small fragments of the 6.5 kg main mass, all recovered fragments are at NHMD.
