Colombia has no fireball camera network. Its phones can be one.

An agent that turns witness videos of a fireball, once each camera has been oriented offline, into its trajectory, its speed and a verdict (a natural meteor, a re-entering satellite, or not enough evidence to tell), with checks in the code that the model cannot skip and a person who signs the report off.

When a fireball crosses the sky, people film it with phones, dashcams and security cameras. Testigos del Bólido reads those videos with Muse Spark, tracks the fireball frame by frame with SAM 3.1, orients each camera against OpenStreetMap landmarks (today an offline step: during development an AI coding assistant, Claude Code, not a Meta model, marked the lines and matched the landmarks), and intersects the cameras' planes of sight into a trajectory with error bars. An agent, Muse Spark 1.3 calling tools in a loop, decides which cameras to trust; the code accepts or refuses each decision on criteria it measures; and the run stops for a person who signs the report off, sends it back with notes, or supplies the evidence the agent asked for.

Validation: Chelyabinsk 2013. Against the published solution (CBET 3423), the fitted heading and slope fall within 3 degrees, and CBET's end point lies 3.7 km from our fitted line. The four criteria committed before the first camera was oriented all pass; a speed criterion added the next day does not. The agent never saw the published values, but the calibrations of the run's cameras were made with them in view. The refereed speeds published later (19.03 and 19.16 km/s) sit within 0.62 km/s of the fit, and a camera left out of the fit agrees on its own clock: 19.17 km/s. After the run was signed, one more camera was oriented with neither the published values nor the fitted path in view; its lines of sight miss that path by 0.26° (median), a check mostly on one of the fit's two cameras, whose planes it nearly shares. In everyday terms, the stretch the two cameras saw is 246 km long, about as far as Bogotá is from Medellín, and one camera followed the fireball from 89 km down to 12 km in 13.7 s; even the low end of the Monte Carlo's 95% speed range, 12.1 km/s, is faster than anything that orbits the Earth can enter the atmosphere.

Open case: Colombia, 30 July 2025. A green fireball crossed north-eastern Colombia at 10:50 pm. GOES-19 saw a 1.05 s flash; no tracked re-entry matches it; the only video analysed so far cannot be oriented. The agent says so, and asks for videos from the towns that would close the geometry. A page in Spanish tells witnesses how to send them.

Built during the hackathon, and what came before: the method (Ceplecha 1987, Borovička 1990), the published solutions, the camera-site catalogue, OpenStreetMap, NASA's GLM catalogue, the Aerospace Corporation's re-entry listings and the witness videos came before. The code, the camera fits, the agent and its checks, the viewer and the witness page were built during the event, from 26 October, with an AI coding assistant (Claude Code).
