Katol is an (L6) ordinary chondrite that fell over the town of Katol, in the Nagpur District of India, the afternoon of May 22, 2012.
The Meteoritical Bulletin (MB 102) describes the fall of the Katol meteorite as a large shower of stones followed by 30 to 50 seconds of sonic booms. At least 30 stones were initially collected, and 13 kg of material have been recovered to date.
Scientists from the Physical Research Laboratory in Ahmedabad visited the area shortly after the spectacular fall to document witness accounts and collect meteoritic material despite temperatures as high as 48C (118F). They recovered meteorite pieces from a local school ground, and photographed a corrugated metal shed roof that had been pierced by a falling stone, as well as a brick in the shed floor that had been dislodged. They also noted that:
"Since, the meteorite shower took place in a varied land cover with city dwellings, railway tracks, roads, agriculture field and barren land with several obstacles, it was difficult to scan through the entire region for recovering the meteorite fragments. Our interactions with many residents of the region revealed that almost each household found a fragment"
While the main mass of Katol is housed at the Geological Survey of India, the type specimen is held in the ASU Center for Meteorite Studies collection due to Center's role in its classification.
Aioun el Atrouss is a diogenite (achondrite) that fell April 17, 1974, in southeastern Mauritania.
According to the Meteoritical Bulletin (MB 56):
A fireball was observed and a sonic boom was heard. Meteoritic material was recovered from three separate sites in sandy, desert terrain by tribesmen.
Aioun el Atrouss is classified as a diogenite-pm, meaning that it is a polymict breccia from the diogenite group.
Part of the HED (Howardites, Eucrites and Diogenites) group of achondrites, diogenites are believed to originate in the crust of Asteroid 4-Vesta. According to radioisotope dating, the HED achondrites crystallized between 4.43 and 4.55 billion years ago. Diogenites are plutonic igneous rocks that form deep in the crust and cool very slowly, resulting in large crystals. They are named for the ancient Greek philosopher Diogenes, who was the first to suggest that meteorites were not terrestrial rocks, and actually originated in space. Photo ASU/CMS.
Monahans (1998) is an (H5) ordinary chondrite that fell in Ward County, Texas, the evening of March 22, 1998.
According to the Meteoritical Bulletin (MB 82
Two stones, weighing 1344 g and 1243 g, fell in the city of Monahans, Texas, after two sonic booms and a fireball were observed over a wide area (up to 100 km from the fall site). One stone penetrated the asphalt on a city street and was found in the sandy subsurface.
The name Monahans is shared by two distinct meteorites; the other, Monahans (1938) is an iron meteorite also found in Ward County, TX, sixty years earlier. The ASU Center for Meteorite Studies houses specimens of both meteorites.
Juancheng is an H5 (ordinary) chondrite that fell late the night of February 15, 1997 in Shandong Province, China.
More than 1,000 individual stones, totaling over 100 kg of material, were subsequently recovered, including one piece that fell through a roof and landed in a pot on the stove!
Lost City is an (H5) ordinary chondrite that fell in Oklahoma, USA, January 3, 1970, at 8:14 PM.
The many witnesses described the associated fireball lighting up the town, and a Smithsonian Astrophysical Observatory Special Report (#336) compared its brightness to that of the full moon. The report goes on to say that:
Sonic booms were reported to have been heard over an area of about 1000 km2 between Tulsa and Tahlequah. well-confirmed reports of the audio event cover an area of at least 300 km2, including Tahlequah, Waggoner, Inola, and Mazie, Oklahoma. This was variously described as like thunder, a single boom, or a series of consecutive sharp cracks.
We were probably only a few hours too late in our recovery to meet the requirements of those biochemists with an interest in organic compounds in meteorites. Judging from the footprints around the meteorite and the stained snow immediately adjacent to it, we believe this object to have been seriously contaminated by a dog or some other canine.
The Lost City fireball was extremely well-documented; it was photographed by 4 Prairie Meteorite Network cameras, and the meteorite was subsequently recovered by the Smithsonian Institution. The data collected through the camera network allowed researchers to calculate the orbit of the meteoroid, and Lost City provided a wealth of information on trajectory, photometry, and impact prediction. While the Smithsonian Institution operated 16 Prairie Meteorite Network camera stations in the mid-western US between 1964 and 1975; over this entire period, Lost City was the only meteorite recovered after its fall was captured by the camera network.
Nuevo Mercurio is an H5 (ordinary) chondrite that fell the evening of December 15, 1978, in Zacatecas, Mexico.
According to the Meteoritical Bulletin (MB 57):
"A bright fireball, traveling NE. to SW. and visible over a radius of at least 200 km, exploded over north-central Mexico and scattered meteorites over an elliptical area more than 10 km in length."
To date, over 300 specimens totaling 50 kg (110 lb) have been recovered.
Leighlinbridge is an (L6) ordinary chondrite that fell the night of November 28, 1999, in County Carlow, Ireland.
According to the Meteoritical Bulletin (MB 84), “a bright fireball accompanied by detonations was observed over Carlow”. In an article from January of 2000, BBC News described the fall as spectacular, and cited witness accounts of the fireball lighting up the night sky and sending out booming explosions.

A Scottish meteorite dealer offered a reward of up to £20,000 for a large piece of the stone, but it wasn’t until 2 weeks later that he was anonymously sent a recovered piece of the meteorite. According to BBC News, the parcel’s delivery had been delayed because it lacked a customs declaration, and it was eventually learned that the meteorite had been found on a road by a local grandmother.
To date, 4 stones totaling 271 g have been recovered.
Manych is an LL3.4 (ordinary) chondrite that fell in the Stavropol region of Russia.
While the first 1.86 kg stone was found shortly after it fell in the village of Manych, October 21, 1951, it wasn’t until years later that a second piece of the Manych meteorite was identified.
The second stone weighed 1.7 kg, and was found in a pasture in 1952. In 1957, this fusion-crusted piece was identified at the Stavropol Local History Museum, after having been brought in by a high school geography teacher.
Carancas is an (H4-5) ordinary chondrite that fell in Peru, the afternoon of September 15, 2007. To date, over 340g of material have been recovered.
According to the Meteoritical Bulletin (MB 93):
A large fireball was witnessed to impact near the community of Carancas, in the province of Chucuito, region of Puno in the country of Peru. It made a sizable impact crater, ~13.8 m in diameter (INGEMMET) or 11-12 m (L. Jackson, CGS). Local residents and many others have recovered numerous pieces of the impactor from the sides of the crater and the surrounding area.

Mayo Belwa is an aubrite (achondrite) that fell August 3, 1974, in the Adamawa district of Nigeria.
According to the Meteoritical Bulletin (MB 55):
A fireball was seen by herdsmen and sounds were heard over an area extending to 25 km from the impact site. The stone was sent to the Geological Survey of Nigeria and smelt strongly of sulphur when first received.
Over 10 lb (4.8 kg) of the Mayo Belwa achondrite were recovered.
