Forrest’ (prov.), Fall on 18 November 2019

The ~ 300-gram Forrest (prov.) meteorite (most likely an ordinary chondrite) which fell northwest of Forrest Airport on 18 November 2019 was found in the second half of July 2020 after about four hours of searching during a 2-week trip to the predicted ~5-km fall area. The meteorite was found within 100 metres from the calculated ‘fall line’. Photo: Raiza Quintero

‘Madura (Cave)’ (prov.), Fall on 19 June 2020

The 1.1-kilogram ‘Madura (Cave)’ (prov.) meteorite of a fall on 19 June 2020 found only twenty days after its fall at a location south of the Eyre Highway on an old telegraph track near Madura Cave. It was found rather by accident by astronomer Dr Hadrien Devillepoix and planetary geologist Dr Anthony Lagain after only two hours while walking back to their car during a one-vehicle ‘scout trip’ to assess the latest only roughly calculated ~2-km fall area near Madura. The meteorite was found less than 15 metres from the predicted ‘fall line’. Photo: Hadrien Devillepoix/DFN

The ‘Madura (Cave)’ bolide (DN200619_01) captured by a camera of the Desert Fireball Network on 19 June 2020. 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
