Madura Cave

Meteorite fall (L5, 1.072 kg) near Madura Cave, Western Australia, Australia, on 20 June 2020 at 6:05 a.m. AWST (22.05 UTC, 19 June)

On or around 9 July 2020 astronomer Dr Hadrien Devillepoix and planetary geologist Dr Anthony Lagain were on a reconnaissance mission to assess the calculated fall area of a bolide recorded by the Desert Fireball Network above the Nullarbor Plain on 19 June 2020. They did some drone recordings of the area and rather by accident while on their way back to the car and after only two hours of walking the calculated fall line during the reconnaissance mission Dr Anthony Lagain saw the 1.072-kg meteorite (~11 × 9 × 8 cm) right on an old telegraph track at location -31.96557, 126.98438 near Madura Cave, south of the Eyre Highway. The bolide’s luminous trail of 5.5 seconds was recorded from an altitude of 75 km down to 18.6 km. For the bolide’s meteoroid a rather unusual preatmospheric Aten asteroid orbit has been calculated. The surprise find was announced in a Curtin University press release on 30 July 2020. On 16 January 2021 the meteorite was officially registered in the Meteoritical Bulletin Database as confirmed fall Madura Cave (L5, W0).

It was found rather by accident by astronomer Dr Hadrien Devillepoix and planetary geologist Dr Anthony Lagain after only two hours during a recon mission to assess the latest calculated fall area near Madura.

Its much less elliptic preatmospheric near-Earth orbit had an apoapsis between the orbits of Earth and Mars and a periapsis between the orbits of Earth and Venus, an Aten asteroid orbit. Photo: DFN
