About this image
I recorded this bright meteor on one of my RMS cameras and also on a UFO Capture camera monitoring the same field. UFO Analyser suggested it was an October Camelopardalid of apparent mag -2.4, although the cloud cover affected this estimate. RMS didn't analyse it, although it was recorded by its fireball detector. Extracting the frames I created this animated GIF.
A 2-station solution with Nick James' RMS station identifies the meteor as a sporadic of absolute magnitude -4.7.
Ground track 0.485 deg W 53.1 deg N to 0.667 deg W 52.748 N
Altitude 100.2 km to 65.1 km
Geocentric velocity 39 km/s
Radiant RA 13 h 19.6 m Dec +72.4 (near the Guardians of the Pole)
It would have been a spectacular sight in the zenith for an observer in the East Midlands

Hi Dominic,
In the UFO program suite, UFO Analyser creates a csv file containing details of each meteor/fireball (site coordinates are encrypted). The csv files from other stations are combined in UFO Orbit to derive ground tracks, radiants, orbits.
A simpler, non-proprietary csv format is available to allow other meteor software to provide data for use in UFO Orbit. (Site coordinates are in readable form).
RMS software creates UFO-compatible csv files in this latter, simpler format. I will send you an example.
Fireballs recorded by RMS have to be processed manually in SkyFit software. This creates an ECSV file in the GFE (Global Fireball Exchange) format. See the project led by Jim Rowe
GitHub - UKFAll/standard: The Global Fireball Exchange standard
GMN (Global Meteor Network) developers of RMS software, use the Python library WMPL

Cheers,
Alex.
