Abstract Previous works have shown that dust particles can be accelerated to marginally relativistic velocities in supernova. In this paper we consider the observational signatures of the interactions of such particles with the Earth’s atmosphere. We develop a hydrodynamic and radiative model to explore the detectability of sub-relativistic meteoroids. We find that a large fraction of the meteoroid energy during its passage through the Earth’s upper atmosphere powers the adiabatic expansion of a hot plasma cylinder, giving rise to acoustic shocks. Additionally, a global network of several hundred all-sky optical cameras with a time resolution of would be capable of detecting sub-relativistic meteoroids.
