On the 27th of November 2015 , at 10:43:45.526 UTC , a fireball was observed across South Australia by ten Desert Fireball Network observatories lasting 6.1 s .
A \sim 37 kg meteoroid entered the atmosphere with a speed of 13.68 \pm 0.09 \mbox { km s } ^ { -1 } and was observed ablating from a height of 85 km down to 18 km , having slowed to 3.28 \pm 0.21 \mbox { km s } ^ { -1 } .
Despite the relatively steep 68.5 ^ { \circ } trajectory , strong atmospheric winds significantly influenced the darkfight phase and the predicted fall line , but the analysis put the fall site in the centre of Kati Thanda - Lake Eyre South .
Kati Thanda has metres-deep mud under its salt-encrusted surface .
Reconnaissance of the area where the meteorite landed from a low flying aircraft revealed a 60 cm circular feature in the muddy lake , less than 50 m from the predicted fall line .
After a short search , which again employed light aircraft , the meteorite was recovered on the 31st December 2015 from a depth of 42 cm .
Murrili is the first recovered observed fall by the digital Desert Fireball Network ( DFN ) .
In addition to its scientific value , connecting composition to solar system context via orbital data , the recover demonstrates and validates the capabilities of the DFN , with its next generation remote observatories and automated data reduction pipeline .
