Mysterious streak of light seen across southern California sky
People across southern California witnessed streaks of light moving across the sky in the early hours of 2 April.
It is unclear what caused the light, though people on social media speculated that it could be debris from a SpaceX launch or a module from the Chinese Shenzhou-15 spacecraft, which was due to enter the atmosphere around the same time.
The BBC is working to verify what may have caused the streaks.
