  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 $\sim37$ kg meteoroid entered the atmosphere with a speed of
13.68$\pm0.09\,\mbox{km s}^{-1}$ and was observed ablating from a height of 85
km down to 18 km, having slowed to 3.28$\pm0.21 \,\mbox{km s}^{-1}$. 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.
