Raw light flux from a bolide observed on 14 August 2019 at 03h07m02s UTC. Red triangles: Dijon FRIPON camera data(30 Hz, 12bits). Blue squares: radiometer prototype data (20 kHz, 14 bits). The faster acquisition rate and the higher amplitude dynamic range of the radiometer allows more detailed observations of the meteor fragmentation and of high speed luminosity variations.
