E-mail: [email protected] (Received 23 April 2005; revision accepted 3 November 2005) Abstract–The L6 ordinary chondrite Villalbeto de la Peña fall occurred on January 4, 2004, at 16:46: 45 r 2 s UTC. The related daylight fireball was witnessed by thousands of people from Spain, Portugal, and southern France, and was also photographed and videotaped from different locations of León and Palencia provinces in Spain. From accurate astrometric calibrations of these records, we have determined the atmospheric trajectory of the meteoroid. The initial fireball velocity, calculated from measurements of 86 video frames, was 16.9 r 0.4 km/s. The slope of the trajectory was 29.0 r 0.6° to the horizontal, the recorded velocity during the main fragmentation at a height of 27.9 r 0.4 km was 14.2 r 0.2 km/s, and the fireball terminal height was 22.2 r 0.2 km. -
