The Junction City meteorite fall from Georgia in 2022 is now published on the Meteoritical Bulletin Database.

Meteoritical Bulletin: Entry for Junction City History: (P. Branch, M. Hankey) At 00.04 local time on 26 September 2022 (0404 UTC), a bright fireball traveling from the S to N detonated above southern Georgia between Atlanta and Columbus. This fireball was widely seen across the southeastern US with 66 reports to the American Meteor Society (eve...

🛑 ASTEROID ATMOSPHERIC ENTRY ALERT ‼️
A freshly discovered small (~1 m diameter) asteroid (CAQTDL2) is in a trajectory that will direct it into the Earth atmosphere, near Luzon island (Philippines), today (Sept. 4th) around 16h 40min UT. No real impact, but a very bright and slow fireball should be observable by people in the area, and meteorites may reach the ground (or the ocean).
Stay tuned for more updates!

Okay meteorite hunters, there appears to be a pallasite (or something similar) waiting to be rediscovered. The following is from

Shepard, C.U. (1860) Notices of several American Meteorites. Amer. J. Sci., 2d ser., vol. 30, pp. 204-208.

"2. Forsyth (Taney County, Missouri) Iron.-My first information of this locality was derived, while on a visit to southeast-
ern Missouri in April last, from N. Aubushon, Esq., of Ironton.
He stated that a small specimen of curiously knitted, malleable
ore, of a white color resembling silver, had been sent him two
or three years ago by a person residing near the locality. Mr.
Aubushon forwarded it to an assayer at Ducktown, Tenn., from
whom he learned that it was composed of iron and nickel. On
visiting St. Louis soon after, I was informed by Proj Swallow,
the State Geologist, that a specimen had also been transmitted
to him by letter from the same place; and that Prof. Litton had
found it to be composed of similar constituents. . Prof Swallow
presented me a small fragment of his specimen, upon which I
am able to offer a few remarks, awaiting the results of Pro!
Litton's analysis, for fuller information.
The mass evidently belongs to the rather rare group of amyg-
daloidal meteoric irons, in which, like those of Steinbach (Sax-
ony) and Hainholz (Westphalia), the peridotic ingredient pre-
ponderates over the nickelic iron. Its specific gravity is 4'46.
The iron is remarkable for its whiteness, while the peridot is of
a well marked green color, and distinctly crystalline. No py-
rites is visible in the very small fragments examined. It is
reported that two considerable mAsses of tbis meteorite were
found buried in tbe soil upon a bill·side j and that they are at
present secreted under the belief that they contain silver."

It only took 165 years, but the meteorite fall Bethlehem is finally classified.

Meteoritical Bulletin: Entry for Bethlehem History: A single 13.9 g stone was found after a significant meteor event that was widely seen and heard over northeastern Massachusetts and New York at around 7:20 am on 11 August 1859.

Remembering our Founding Director Carleton Moore on his birthday.

Very pleased to share our new paper on the Tarda and Tagish Lake meteorites (Schrader et al., 2024), which shows how similar they both are, and suggests that D-type and P-type asteroids may be fragments of the same parent body. We also identified potential parent asteroid sources for Tarda and Tagish Lake! It will be exciting to see what we learn from the Lucy and MMX missions!
This link will give you access to the paper until Sept. 6th, 2024

The long-lost meteorite fall from Alabama (Addison, H4, fall 2012) is finally approved. See

https://www.lpi.usra.edu/meteor/metbull.php?code=83275

Getting this approved was a group effort and thanks to all including Robert Ward (who found the stone), Mike Hankey, Mark Fries, and Axel Wittmann, and members of the NomCom who helped me understand the petrologic differences between an OC4 and 5. The type specimen is in the ASU Buseck Center for Meteorite Studies.

The Tarda meteorite is a nanosponge - but don't make it wet! More details can be found in our recent publication available at

April’s Meteorite of the Month is L’Aigle, an ordinary (L6) chondrite that fell in Orme, France on April 26, 1803.

Several slices of the Mvskoke Merkv meteorite fall (Oklahoma, 20 January 2023) in the ASU Buseck Center for Meteorite Studies. see https://www.lpi.usra.edu/meteor/metbull.php?code=81832

Mvskoke Merkv (pronounced "muh-skō-gee myth-guh") is now an approved meteorite fall. see https://www.lpi.usra.edu/meteor/metbull.php?code=81832

Thank you to all who helped get this classified, and especially Dr. Kathryn (Kat) Gardner-Vandy (citizen of the Choctaw Nation of Oklahoma) of Oklahoma State University, who worked with Jordan Squire of the Mvskoke Language Department at the Muscogee Nation, Muscogee Nation Secretary of Education Kaila Harjo, and Muscogee Nation Principal Chief David Hill who proposed the meteorite’s name. Mvskoke Merkv means "Muscogee Blessing" in the Mvskoke (Creek) language to celebrate this meteorite's fall onto the Muscogee Nations’s federally recognized land.

SESE grad student Anuva Anannya showed the structure of a dust grain older than the Sun with both cirumatellar and interstellar parts. A great first conference talk!

SESE graduate student Sam Courville presenting ferrovulcanism as an explanation for the low density of asteroid Pysche.

Want to better understand the mechanical properties of carbonaceous chondrites, and asteroid regolith from Bennu and Ryugu? Talk to postdoc Keana Jardine and Prof. Christian Hoover.

Back-to-back talks at LPSC from SESE student Cassandra Craver and BCMS postdoc Imene Kerraouch introducing the cosmic Tw***ie from Ryugu and an equilibriated clast (CM6) with links to the bright boulders on Bennu.

The Buseck Center for Meteorite Studies and School of Earth and Space Exploration are pleased to announce the winners of the 2024 Nininger Student Travel Award. The goal of this award is to support attendance of the annual Lunar and Planetary Science Conference (LPSC) for at least 4 undergraduate and/or graduate students to present their latest research.

Sit back, zoom in, and enjoy the beauty of the beginnings of our solar system.

The final portion of asteroid material collected by our OSIRIS-REx spacecraft has been revealed, and this super high-resolution image allows you to zoom in and admire every detail of the rocks and dust from Bennu.

You are seeing particles from a planetary body millions of miles from Earth and more than four billion years old. Each grain could hold knowledge that will help us unlock the secrets of how our solar system formed. From carbon to amino acids and even serpentine water-bearing clay minerals, this is just the beginning for our studies of Bennu.

The curation team at NASA's Johnson Space Center in Houston is nearing the end of disassembling the TAGSAM (Touch-and-Go-Sample-Acquisition) head, after which the final bits of asteroid material will be weighed, containerized, and stored as part of the most extensive astromaterials collection in the world, for scientists now and generations from now.
