C/2014 UN271 (Bernardinelli-Bernstein) is a comet incoming from the Oort cloud which is remarkable in having the brightest (and presumably largest) nucleus of any well-measured com…
Triple-frequency meteor radar full wave scattering Measurements and comparison to theory
G. Stober, P. Brown, M. Campbell-Brown +1
Context. Radar scattering from meteor trails depends on several poorly constrained quantities, such as electron line density, q, initial trail radius, r0, and ambipolar diffusion c…
No Activity Among 13 Centaurs Discovered in the Pan-STARRS1 Detection Database
Eva Lilly, Henry Hsieh, James Bauer +5
Centaurs are small bodies orbiting in the giant planet region which were scattered inwards from their source populations beyond Neptune. Some members of the population display come…

Characterizing the Manx Candidate A/2018 V3
Caroline Piro, Karen J. Meech, Erica Bufanda +10
Manx objects approach the inner solar system on long-period comet (LPC) orbits with the consequent high inbound velocities, but unlike comets, Manxes display very little to no acti…
Establishing Earth's Minimoon Population through Characterization of Asteroid 2020 CD
Grigori Fedorets, Marco Micheli, Robert Jedicke +20
We report on our detailed characterization of Earth's second known temporary natural satellite, or minimoon, asteroid 2020 CD3. An artificial origin can be ruled out based on its a…
A Single-chord Stellar Occultation by the Extreme Trans-Neptunian Object (541132) Leleākūhonua
Marc W. Buie, Rodrigo Leiva, John M. Keller +32
A stellar occultation by the extreme large-perihelion trans-Neptunian object (541132) Leleākūhonua (also known by the provisional designation of 2015 TG387) was predicted by the Lu…
High precision meteor observations with the Canadian Automated Meteor Observatory -- Data reduction pipeline and application to meteoroid mechanical strength measurements
Denis Vida, Peter G. Brown, Margaret Campbell-Brown +3
Context. The mirror tracking system of the Canadian Automated Meteor Observatory (CAMO) can track meteors in real time, providing an effective angular resolution of 1 arc second an…
Coordinated Optical and Radar Measurements of Low Velocity Meteors
Peter Brown, Robert J. Weryk
To better estimate which luminous efficiency () value is compatible with contemporary values of the ionization coefficient (), we report a series of simultaneous optical and…
Precision measurements of radar transverse scattering speeds from meteor phase characteristics
Michael Mazur, Petr Pokorny, Peter Brown +5
We describe an improved technique for using the backscattered phase from meteor radar echo measurements just prior to the specular point () to calculate meteor speeds and th…
Possible Interstellar meteoroids detected by the Canadian Meteor Orbit Radar
Mark Froncisz, Peter Brown, Robert J. Weryk
We examine meteoroid orbits recorded by the Canadian Meteor Orbit Radar (CMOR) from 2012-2019, consisting of just over 11 million orbits in a search for potential interstellar mete…
