FRIPON: a worldwide network to track incoming meteoroids

Meteoritical Bulletin 109 contains the 2790 meteorites approved by the Nomenclature Committee of the Meteoritical Society in 2020. It includes 17 falls (Al Farciya, Auckland, Cavezzo, Flensburg, Gatuto, Kolang, Mahadeva, Matarka, Narashino, Novo Mesto, Oslo, Saint‐Ouen‐en‐Champagne, Santa Filomena, Tarda, Tiros, Wad Lahteyba, Zhob), with 2336 ordinary chondrites, 131 carbonaceous chondrites (including 8 ungrouped ones), 123 HED achondrites, 41 Martian meteorites, 35 lunar meteorites, 23 iron meteorites, 21 ureilites, 17 primitive achondrites, 13 ungrouped achondrites, 12 mesosiderites, 12 Rumuruti chondrites, 9 enstatite chondrites, 8 pallasites, 4 unclassified meteorites (identified at the surface of Mars), 3 enstatite achondrites, 1 angrite, and 1 ungrouped chondrite. One thousand five hundred and forty‐one are from Antarctica, 763 from Africa, 297 from South America, 127 from Asia, 31 from North America, 11 from Europe, 10 from Oceania, 9 from Mars, and 1 from an unknown location.

“…The astrometric reduction of fireballs involved hitherto a complex and tedious processes that generally required several manual tasks. The future of fireball analysis is oriented towards complete automation of the process, as demonstrated by the latest efforts made by the detection networks (Colas et al 2020). To streamline the study of meteors, we have developed a software called 3D Fireball Trajectory and Orbit Calculator (3D-FireTOC), an automatic Python code for detection, trajectory reconstruction of meteors and heliocentric orbit computation from CCD recordings.…”

The disruption of asteroids and comets produces cm-sized meteoroids that end up impacting the Earth's atmosphere and producing bright fireballs that might have associated shock waves or, in geometrically-favorable occasions excavate craters that put them into unexpected hazardous scenarios. The astrometric reduction of meteors and fireballs to infer their atmospheric trajectories and heliocentric orbits involves a complex and tedious process that generally requires many manual tasks. To streamline the process, we present a software package called SPMN 3D Fireball Trajectory and Orbit Calculator (3D-FireTOC), an automatic Python code for detection, trajectory reconstruction of meteors, and heliocentric orbit computation from video recordings. The automatic 3D-FireTOC package comprises of a user interface and a graphic engine that generates a realistic 3D representation model, which allows users to easily check the geometric consistency of the results and facilitates scientific content production for dissemination. The software automatically detects meteors from digital systems, completes the astrometric measurements, performs photometry, computes the meteor atmospheric trajectory, calculates the velocity curve, and obtains the radiant and the heliocentric orbit, all in all quantifying the error measurements in each step. The software applies corrections such as light aberration, refraction, zenith attraction, diurnal aberration and atmospheric extinction. It also characterizes the atmospheric flight and consequently determines fireball fates by using the 𝛼 − 𝛽 criterion that analyses the ability of a fireball to penetrate deep into the atmosphere and produce meteorites. We demonstrate the performance of the software by analyzing two bright fireballs recorded by the Spanish Fireball and Meteorite Network (SPMN).

“…Over 40 meteorite falls in total have been recovered with the assistance of fireball observations (Colas et al., 2020; Devillepoix et al., 2020; Gardiol et al., 2021; Granvik & Brown, 2018). The most numerous of the meteorite fall types recovered are H chondrites.…”

On June 1, 2019, just before 7:30 p.m. local time, the Desert Fireball Network (DFN) detected a −9.3 magnitude fireball over South Australia near the Western Australia border. The event was observed by six fireball observatories, and lasted for 5 s. One station was nearly directly underneath the trajectory, greatly constraining the trajectory solution. This trajectory's backward numerical integrations indicate that the object originated from the outer main belt with a semimajor axis of 2.75 au. A light curve was also extracted and showed that the body experienced very little fragmentation during its atmospheric passage. A search campaign was conducted with several DFN team members and other volunteers. One 42 g fragment was recovered within the predicted fall area based on the dark flight model. Based on measurements of short‐lived radionuclides, the fragment was confirmed to be a fresh fall. The meteorite, Arpu Kuilpu, has been classified as an H5 ordinary chondrite. This marks the fifth fall recovered in Australia by the DFN, and the smallest meteoroid (≃2 kg) to ever survive entry and be recovered as a meteorite.
