Abstract:
In this work we present one of the most spectacular fireball events detected by the MOROI (Meteorite Orbits Reconstruction by Optical Imaging) (Nedelcu et al. 2018) part of the FRIPON (Fireball Recovery and Inter Planetary Observation Network) (Colas et al. 2020) all-sky camera network. The meteor was recorded on 3rd of November 2022 at 01:30:03 UT by cameras Bacau (ROBC01), Paulesti (ROPH01) and Obarsia Noua (ROOT01). The ablation phenomenon started at an altitude of 95 km above the sea level and the meteoroid fainted/ left the Earth’s atmosphere at 90.6 km. The fireball event had a duration of 12.22 seconds. We determine the physical parameters of the meteoroid resulting from the luminous trajectory (Gritsevich 2008, 2009, Sansom et al. 2019, Boaca et al. 2022). We compute its mass, its velocity and determine the orbital elements using Meteor Toolkit (Dmitriev et al. 2015). Boaca I., et al. (2022), ApJ, 936, 150.Colas, F., et al.
