A Cloud-Based Tool for Meteorite Recovery Using Drones and Machine Learning
Seamus L. Anderson, Hadrien A. R. Devillepoix, Lewis Lakerink +30
We present a cloud-based tool that uses drones and machine learning to help recover instrumentally observed meteorite falls. We showcase a collection of improvements made upon prev…
Model Predictions for the 2025 October Draconid Outburst
Auriane Egal, Paul Wiegert, Danielle E. Moser +2
The October Draconid meteor shower, produced by comet 21P/Giacobini-Zinner, is notorious for rare but intense outbursts, some exceeding rates of about 10 000 meteors per hour. In 2…
Catastrophic disruption of asteroid 2023 CX1 and implications for planetary defense
Auriane Egal, Denis Vida, François Colas +94
Mitigation of the threat from airbursting asteroids requires an understanding of the potential risk they pose for the ground. How asteroids release their kinetic energy in the atmo…
A limit on the mass of the Taurid Resonant Swarm at sub-100 meter sizes
Paul Wiegert, Denis Vida, David L. Clark +3
We report on a pencil-beam survey of the Taurid Swarm, a possible concentration of bodies in the Taurid meteoroid stream associated with the 7:2 mean-motion resonance with Jupiter.…
Observations of the new meteor shower from comet 46P/Wirtanen
D. Vida, J. M. Scott, A. Egal +5
A new meteor shower -Sculptorids produced by the comet 46P/Wirtanen was forecast for December 12, 2023. The predicted activity was highly uncertain, but generally considered to…
First holistic modelling of meteoroid ablation and fragmentation: A case study of the Orionids recorded by the Canadian Automated Meteor Observatory
Denis Vida, Peter G. Brown, Margaret Campbell-Brown +1
18 mm-sized Orionid meteoroids were captured in 2019 and 2020 by the Canadian Automated Observatory's mirror tracking system. Meteor position measurements were made to an accuracy…
Modelling the 2022 τ-Herculid outburst
Auriane Egal, Paul A. Wiegert, Peter G. Brown +1
The -Herculids (IAU shower number #61 TAH) is a minor meteor shower associated with comet 73P/Schwassmann-Wachmann 3, a Jupiter-Family comet that disintegrated into several frag…
A Proposed Alternative Dynamical History for 2P/Encke which Explains the Taurid Meteoroid Complex
A. Egal, P. Wiegert, P. G. Brown
The Taurid Meteoroid Complex (TMC) is a broad stream of meteoroids that produces several annual meteor showers on Earth. If the linkage between these showers and 2P/Encke is at the…
An observational synthesis of the Taurid meteor complex
A. Egal, P. G. Brown, P. Wiegert +1
We provide an overview of the observational properties of the four major Taurid showers, namely the Northern and Southern Taurids (#017 NTA and #002 STA), the Beta Taurids (#173 BT…
A dynamical analysis of the Taurid Complex: evidence for past orbital convergences
A. Egal, P. Wiegert, P. G. Brown +3
The goal of this work is to determine if the dynamics of individual Taurid Complex (TC) objects are consistent with the formation of the complex via fragmentation of a larger body,…
Modeling the past and future activity of the Halleyids meteor showers
Auriane Egal, Paul Wiegert, Peter G. Brown +2
We present a new numerical model of the eta-Aquariid and Orionid meteor showers. The model investigates the origin, variability and age of the eta-Aquariid and Orionid apparitions…
Activity of the Eta-Aquariid and Orionid meteor showers
A. Egal, P. G. Brown, J. Rendtel +2
We present a multi-instrumental, multidecadal analysis of the activity of the Eta-Aquariid and Orionid meteor showers for the purpose of constraining models of 1P/Halley's meteoroi…
A new method for measuring the meteor mass index: application to the 2018 Draconid meteor shower outburst
Denis Vida, Margaret Campbell-Brown, Peter G. Brown +2
Context. Several authors predicted an outburst of the Draconid meteor shower in 2018, but with an uncertain level of activity. Aims. Optical meteor observations were used to derive…
Dust Production of Comet 21P/Giacobini-Zinner Throughout its 2018 Apparition
Steven Ehlert, Natalie Moticska, Auriane Egal
We present the results of a long term telescopic observation campaign of comet 21P/Giacobini-Zinner, parent body of the Draconid meteor shower, spanning days during its…
Meteor shower forecasting in near-Earth space
Althea V. Moorhead, Auriane Egal, Peter G. Brown +2
NASA's Meteoroid Environment Office (MEO) produces an annual meteor shower forecast in order to help spacecraft operators assess the risk posed by meteoroid streams. Previously, th…
The Draconid meteoroid stream 2018: prospects for satellite impact detection
Auriane Egal, Paul Wiegert, Peter G. Brown +3
Predictions of the 2018 Draconid activity at the Earth and the Sun-Earth L1 and L2 Lagrange points are presented. Numerical simulations of the meteoroids' ejection and evolution fr…
