History: On the afternoon of 19 April 2018, a large fireball detonated over the Nigerian state of Oyo. This fireball was recorded by NASAs Center for Near Earth Object Studies (CNEOS) as event 2018-04-19 14:02:27. The meteoroid entered at 20.9 km/s and detonated at an altitude of 30 km at 7.5’N, 3.6’E releasing a calculated total impact energy of 0.23 kt. Many stones fell between the villages of Ipapo (8°7’50.84"N, 3°30’34.58"E) and Tede to the north (8°33’21.49"N, 3°26’46.31"E). Stone were collected at multiple locations. The meteorite is named for the village of Aba Panu near the center of the strewn-field: multiple kg-sized stones were found in and around this village. Current total known weight is near 160 kg. Physical characteristics: The stones are hard, range from 30 g to near 40 kg, rounded with broad poorly developed regmaglypts, and largely lacking fusion crust. Fusion crust is occasionally preserved within the shallow regmaglypts. Most stones are greyish green and show areas of rounded to angular light-colored clasts. Largest clast (5 × 2 cm) is angular, fine-grained, and achondritic. Observations from multiple slices show that clasts constitute roughly

History: On May 1, 2015, Xueming Tang, a Chinese amatuer, and his companions found this sample in the Bayin Gobi desert. He then sent a 20 g sample, cut from the main rock, to GUT for classification and description. The finder retained the main mass. Physical characteristics: Total mass: 35 kg (1 piece), no fusion crust, black-brown surface, smoky-gray colored interior. Petrography: The meteorite consists mainly of a medium-grained granular aggregate of olivine, low-Ca pyroxene and feldspar, with minor amounts of Fe-Ni alloy and troilite. The chondrules are moderately abundant and are readily defined. Geochemistry: Minerals are uniform. Olivine: Fa=26.1±0.7 (n=12); low-Ca pyroxene: Fs=21.9±0.3Wo=1.6±0.3 (n=11). Classification: Ordinary chondrite (L5); S2; W1. Specimens: About 20 g sample and one thin sections are deposited in GUT.

History: Reports of a meteor that detonated in a loud explosion, and stones falling from the sky into the town of Benenitra (pop. ~30,000) on the evening of July 27, 2018, were received by a visiting geologist, Timothy Marais, on July 30, 2018. He was shown photographs and several small fragments, two of which he purchased, weighing 99 and 14 g. Roger Gibson and Lewis Ashwal in the School of Geosciences at the University of the Witwatersrand confirmed a meteorite origin for these specimens using petrographic analysis and EMPA. Confirmation of the date and time of the fall was obtained independently when an upper atmosphere infrasound event was identified on a bearing south-southwest of the CTBTO station IS33 near Antananarivo, Madagascar, at 17h16 GMT on July 27 by Dr. Andry Ramanantsoa (Laboratory of Seismology and Infrasound, University of Antananrivo). A weak ground tremor at approximately 17h17 GMT was identified in the data from the seismograph at the Sakaraha (SKRH) station approximately 80 km northwest of Benenitra by Dr Ranto Raveloson (Wits), and was interpreted to be related to the airburst. Magnetic susceptibility measurements were performed by Prof. Susan Webb (Wits). Physical characteristics: Two broken fragments containing small remnants of bluish-black to brown-black fusion crust and weighing 14 g and 82 g (after thin sectioning) consist of a light-gray matrix with disseminated metal (<1 mm) and some visible chondrules (<5 mm). The edge of the larger fragment, which contains a thin (
