The Cali meteorite fall occurred on 6 July 2007 at 21h33m±1m UTC. In a recent paper we characterised this meteorite as a new H/L ordinary chondrite, and also studied the circumstances of this fall. In total, 10 meteorite samples with a total mass of 478 g were recovered around 3º24.3'N, 76º30.6'W.
Most of the specimens found were quickly identified as meteorites because they exhibited a prominent fusion crust covering part of their surface. Two astronomical associations, the sociación de Astrónomos Aficionados de Cali (ASAFI) and the Escuela de Astronomía de Cali (EAC) participated in the recovery.
They also collected bolide reports in several municipalities of the Cauca Valley. Some eyewitnesses heard audible detonations a few minutes later of seeing the bolide. In the following minutes some meteorites penetrated the roofs of several houses on the outskirts of Cali. The interior of those pieces that broke during impact appear granular and dominated by large chondrules. Most of the large pieces were broken, but the small ones are completely fusion crusted. The meteorite appears to be brecciated.

Title: The Cali Meteorite: Luminescence of a recently fallen H/L ordinary chondrite
Authors: J. M. Trigo-Rodríguez, J. Llorca and D. W.G. Sears

The Cali meteorite fall occurred on 6 July 2007 at 21h33mr1m UTC. Some specimens were recovered just after their fall so they are extremely fresh materials. Mineral analysis and bulk chemistry revealed that the measured abundances for most elements closely match the values recorded for other ordinary chondrites classified as H/L. We present here thermoluminescence studies of this recently fallen meteorite in order to get additional information on the radiation environment, and the thermal history of this meteorite. Such information is revealed to be complementary with the range of orbital elements deduced from eyewitness reports of the fireball.

Here at Sky & Telescope we get wind of all kinds of reports of meteorite falls. Few are legitimate. But on July 6th the sky really was falling over South America, when an incoming object broke apart in the lower atmosphere with a trio of ferocious explosions that shattered windows and shook the ground violently. Moments later, stones rained from the sky and pelted homes in the poor barrios surrounding the notorious city of Cali, Colombia.

Cali Colombia Meteorite - Fell July 6, 2007 at ~4:10 PM
This stone impacted the home of Yuly Melecio in the Barrio Mariano Ramos neighbourhood of Cali. She lives on the second floor of a building and the stone impacted her rooftop and penetrated both the zinc metal and ceramic roof tiles.

Según habitantes de la vivienda, el trozo de piedra traspasó una lámina de zinc del techo de la cocina. Miembros de asociaciones de astrónomos aseguran que éste corresponde a restos del meteoro que habría explotado en el centro del Valle.
Un fragmento de lo que sería el meteoro o bólido que habría caído el pasado viernes en el Valle del Cauca fue encontrado en una vivienda al oriente de Cali, según se conoció ayer.
El pedazo de piedra, explicó Jackeline García, quien habita la casa situada en el barrio Laureano Gómez, cayó después de las 4:00 p.m.
La señora García dijo que tuvo una extraña sensación, pues escuchó truenos, pese al inclemente sol que hacía ese día.
