The fireball was observed by six observatories of the Desert Fireball Network (DFN), a continental scale facility optimised to recover meteorites and calculate their pre-entry orbits. The 30cm meteoroid entered at 15.44 km s-1, followed a moderately steep trajectory of 51\u00b0 to the horizon from 81 km down to 19 km altitude, where the luminous flight ended at a speed of 3.2 km s-1. Deceleration data indicated one large fragment had made it to the ground. The four person search team recovered a 1.15 kg meteorite within 130 m of the predicted fall line, after 8 hours of searching, 6 days after the fall. Dingle Dell is the fourth meteorite recovered by the DFN in Australia, but the first before any rain had contaminated the sample. By numerical integration over 1 Ma, we show that Dingle Dell was most likely ejected from the main belt by the 3:1 mean-motion resonance with Jupiter, with only a marginal chance that it came from the nu6 resonance. This makes the connection of Dingle Dell to the Flora family (currently thought to be the origin of LL chondrites) unlikely.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Hadrien A. R.
