Abstract:
The fall of the Cali meteorite took place on 6 July 2007 at 16 h 32 ± 1 min local time (21 h
32 ± 1 min UTC). A daylight fireball was witnessed by hundreds of people in the Cauca Valley in
Colombia from which 10 meteorite samples with a total mass of 478 g were recovered near 3°24.3′N,
76°30.6′W. The fireball trajectory and radiant have been reconstructed with moderate accuracy. From
the computed radiant and from considering various plausible velocities, we obtained a range of orbital
solutions that suggest that the Cali progenitor meteoroid probably originated in the main asteroid belt.
Based on petrography, mineral chemistry, magnetic susceptibility, thermoluminescence, and bulk
chemistry, the Cali meteorite is classified as an H/L4 ordinary chondrite breccia.
