UKFAll - The UK Fireball Alliance

The UK Fireball Alliance aims to recover freshly-fallen meteorites in the UK.  Led by staff of the Natural History Museum, UKFAll is a collaboration between the UK’s meteor camera networks.

The Science

  • About 65,000 meteorites have been found world-wide

  • Only about 40 of these 65,000 were photographed as they arrived as a fireball, including of course the Winchcombe meteorite on 28th February 2021

  • Meteor camera networks photograph incoming meteors from multiple locations

  • That allows the meteor’s path through the atmosphere to be calculated accurately

  • From this, the meteorite’s likely landing point can be estimated

  • This helps us find it before it gets rained on or very contaminated

  • The object’s orbit before hitting the Earth can also be calculated.

  • So, we have a freshly-recovered object and we know where in the solar system it came from; a really powerful combination that helps us understand the solar system.

  • Also, the meteorite’s strength, density and composition can be compared with its path through the atmosphere to learn more about the physics of meteorite and comet impacts.

The People

UK-based members of the UKFAll team include the coordinators of each of the UK fireball camera networks, plus academic staff of UK institutions involved in space science, geology or in the study and curation of meteorites.

Overseas members include the coordinators of some of the international fireball networks and specialists in trajectory, orbit and strewn field calculations.

UKFAll's current postholders are - Jim Rowe, Organiser, and Dr Luke Daly, Treasurer.  UKFAll is affiliated to the Geologists' Association.

The Camera Networks

The participating UK meteor camera networks are:

Cameras 1 and 2.jpg

Get your own camera and join us!  All welcome.

For a brief overview of how to build your own fireball camera for about £200, please see here:

If you would rather buy a pre-built system for about £250 and can wait for UK-based volunteers to build it then visit:

If you can't wait, you can get a pre-built system more quickly at:

For information on the UK meteor networks that you can join, see below - feel free to join one or both:

UK Meteor Observation Network (includes lots of useful utilities and daily meteor and fireball triangulation reports) 

And also the NEMETODE Network

Do it in any order you like - build or buy the camera then join the networks, or join the networks then get some support to build the camera. 


Report a fireball

Have you seen a really bright meteor?  Or heard a sonic boom that isn't related to aircraft movement?  If so, please click the button below to report it.  If a meteorite fell, your report may help us find it.
