Murrili meteorite

Blobrana · L

Murrili 29.26089°S, 137.53765°E
South Australia, Australia
Confirmed fall: 2015 Nov 27
Classification: Ordinary chondrite (H5)
History: The Murrili fireball was imaged by observatories of the Desert Fireball Network, and witnessed by local people at William Creek and Maree, as it blazed through the skies of South Australia around 9:15 pm on November 27, 2015. The object encountered the Earth close to its perihelion point, entering the atmosphere at 13.7 km/s. The object stopped ablating at an altitude of 18.32 km over Kati Thanda-Lake Eyre South. Its darkflight and fall position were modelled using a WRF climate model. An initial aerial search (2 weeks after the fall) revealed a small crater-like impact in the surface of the salt lake. The Arabana people are the traditional custodians of this land. Just after Christmas, with their permission and help - two Arabana men assisted with the search - the ground-based search team set out to collect the rock before rain erased evidence of the fall. On New Year's Eve, a second aerial reconnaissance pinpointed the fall site. After some digging, the meteorite was pulled up through the salt-rich clay mud of the lake. It was recovered 218 m from the calculated fall line. The meteorite had punched a cylindrical hole through the mud and came to rest 43 cm below the surface.

RE: Lake Eyre meteorite

The meteorite fall was witnessed on 27 November [2015] by a number of locals in the William Creek and Marree areas, and captured by Desert Fireball Network cameras stationed at William Creek, Mount Barry, Billa Kalina and Wilpoorina.
Desert Fireball Network team members then went to work on image analysis, triangulation and dynamic calculations in order to locate the fall site in Kati Thanda-Lake Eyre

In a race against time, the geologists dug the 1.7 kilogram meteorite out just hours before heavy rains would have wiped away any trace of it.
The team from Curtin University had been trying to track the fall site since the meteorite was spotted by locals and five remote cameras in late November in the William Creek and Marree areas.
But on New Year's Eve, as heavy rains brewed a downpour, the team found their needle in a haystack.

Rare meteorite offers clues to the universe's formation

A meteorite unveiled in Perth could offer science more clues on how the universe was formed because scientists believe they know where it came from.
The chondrite or stony meteorite was discovered thanks to a network of 32 remote cameras spread throughout Western and South Australia.
Not only could Curtin University's Desert Fireball Network track its location to South Australia's Lake Eyre, but the team believes it could possibly find the asteroid it came from.
