Overview
- The UK Space Agency and the National Space Operations Centre said the timing and trajectory align with the Zhuque‑3 launch at 04:02 GMT and an overflight around 05:00 GMT, and they reported no threat to the public.
- Astrophysicist Jonathan McDowell told the BBC the display was from the Chinese Zhuque‑3 on its first test flight, noting such upper stages are known to create long, linear propellant‑dump trails.
- The bright, straight trail was filmed and photographed between 5:00 and 5:30 a.m. on December 3 from multiple locations, including Gloucestershire, Devon and parts of eastern England.
- Witnesses such as Tim Jackson and Ellie Jarvis captured the feature as it brightened before dawn and then faded, while astrophotographer Tim Burgess recorded it moving across the sky.
- Alternative ideas like a meteor, a jet contrail or an atmospheric light pillar were discounted by experts, with physicist Les Cowley citing the trail’s brightness, height and narrowness as inconsistent with ice‑crystal pillars.
