Description
The All-sky Meteor Orbit System (AMOS), developed at Comenius University in Bratislava, is a global network of autonomous meteor cameras designed to investigate the dynamical and physical properties of meteoroids entering the Earth's atmosphere up to about +3 magnitude. Combining multi-station video observations with meteor spectroscopy (AMOS-Spec), the network provides atmospheric trajectories, pre-atmospheric heliocentric orbits, photometric characteristics, and information on meteoroid composition.
This presentation will highlight selected AMOS results, focusing on bright fireballs and the identification of potentially meteorite-dropping events. Meteor emission spectroscopy provides important constraints on the composition and physical diversity of incoming material. Combined with trajectory reconstruction and orbital analysis, these observations help distinguish different meteoroid material and characterization.
Special attention will be given to the relevance of AMOS observations for planetary defence, including the characterization of small impactors, estimation of their physical properties, and prediction of potential meteorite fall areas. The presentation will discuss the capabilities and limitations of ground-based meteor networks and the potential integration of optical and spectroscopic observations into coordinated planetary defence activities.
