Murrili Meteorite

Murrilli (Moo-da-lee) is an ordinary chondrite of subclass type H5. It is the third meteorite to be recovered using the Australia Desert Fireball Network (DFN) camera observatory. It was observed to fall on 27 November 2015 at 9:15pm local time (10:43:44.50 UTC) in South Australia, and recovered by the DFN team on 31 December 2015 from the Lake Eyre region. As this region is a salt lake, the 1.68 kg rock punched a hole through the ground and was found 0.43 m below the surface. It was recovered 218m from the predicted fall line location. The Arabana people are the traditional custodians of this land, and recovery of this rock would not have been possible without their permission and assistance. After an aerial search two weeks after the recorded fall, ground-based teams, assisted by the two Arabana people, pinpointed the location and subsequently recovered the rock from the salt lake, prior to rain washing away the impact hole.
