From one camera to a trajectory
Watch a meteor's passage and compare the lingering trail from three viewpoints. Explore how independent investigators turned public recordings into a physical track.
What to keep in mind
The asteroid airburst is established. The photographs show its aftermath, not the moving rock, and these selected views are only a small part of the wider research archive.
Separate flight and trail
In the dashcam recording, distinguish the moving bright source from the trail it leaves. Which parts change after the bright source has passed?
Compare the viewpoints
Compare the Yekaterinburg and Chelyabinsk trail photographs. Which differences could follow from viewpoint and an evolving plume rather than a different object?
Find calibration clues
What buildings, wires or horizon details in the street view could help recover a camera direction? Note what a separate star calibration would still add.
