In June 2019 the Earth will approach within 5° mean anomaly of the centre of the Taurid resonant swarm, its closest post-perihelion encounter with Earth since 1975. This will be the best viewing geometry to detect and place limits on the number of NEOs proposed to reside at the swarm centre until the early 2030s. We present an analysis of the optimal times and pointing locations to image NEOs associated with the swarm.

A dynamical analysis of the Taurid Complex: evidence for past orbital convergences

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, or if the

A Fireball and Potentially Hazardous Binary Near-Earth Asteroid (164121) 2003 YT1

We present a fireball detected in the night sky over Kyoto, Japan on UT 2017 April 28 at by the SonotaCo Network. The absolute visual magnitude is = −4.10 ± 0.42 mag. Luminous light curves obtain a

The Cape York Meteorites, the Younger Dryas, and Their Possible Association with the Hiawatha and Paterson Impact Craters

The recent discovery of the Hiawatha and Paterson impact craters in north-western Greenland has motivated three intriguing questions: are they associated with the Cape York meteorites, did they form

Location, orbit, and energy of a meteoroid impacting the Moon during the lunar eclipse of 2019 January 21

During lunar eclipse of 2019 January 21, a meteoroid impacted the Moon producing a visible light flash. The impact was witnessed by casual observers offering an opportunity to study the phenomenon

Solar System Physics for Exoplanet Research

Over the past three decades, we have witnessed one of the great revolutions in our understanding of the cosmos—the dawn of the Exoplanet Era. Where once we knew of just one planetary system (the

An Improved Method to Measure Head Echoes Using a Meteor Radar

We present an improved methodology to obtain absolute position and velocity of meteor head echoes, which can yield orbital information, generally limited to the use of High-Power, Large-Aperture



Discovery of a new branch of the Taurid meteoroid stream as a real source of potentially hazardous bodies

Taurid meteor shower produces prolonged but usually low activity every October and November. In some years, however, the activity is significantly enhanced. Previous studies based on long-term

Meteor observations in Japan: new implications for a Taurid meteoroid swarm

Observational evidence is sought that the long-term (104 yr) action of a mean motion resonance with Jupiter can produce structure in a meteoroid stream, concentrating meteoroids in a dense swarm.

Asteroids in the Taurid Complex

We show that a statistically significant number of Earth-crossing asteroids are part of the Taurid Complex of interplanetary objects. We also identify another group which appears aligned with (2212)

The Running of the Bulls: A review of Taurid fireball activity since 1962

Model predictions based upon the existence of a 7:2 mean motion resonance with Jupiter suggest that in about 20% of Taurid meteoroid stream encounters enhanced numbers of meteors and fireballs should

Enhanced activity of the Southern Taurids in 2005 and 2015

The paper presents an analysis of Polish Fireball Network (PFN) observations of enhanced activity of the Southern Taurid meteor shower in 2005 and 2015. In 2005, between October 20 and November 10,

The orbital dispersion of the macroscopic Taurid objects

If the Taurid Complex asteroids (plus 2PlEncke) are derived from the fragmentation of a giant comet over the past 20-30 kyr, as we have suggested elsewhere, then we need to identify some mechanism

Spectral properties of the largest asteroids associated with Taurid Complex

Context. The Taurid Complex is a massive stream of material in the inner part of the Solar System. It contains objects spanning the range of 10 −6 ‐10 3 m, considered by some authors to have a common

2015 Southern Taurid fireballs and asteroids 2005 UR and 2005 TF50

On the night of Oct 31, 2015 two bright Southern Taurid fireballs occurred over Poland, being one of the most spectacular bolides of this shower in recent years. The first fireball - PF311015a Okonek

Distinct meteoroid families identified on the lunar seismograms

We reexamined the seismic events originating from impacts of meteoroids on the lunar surface, as recorded by the Apollo lunar seismic network, in terms of (1) difference in temporal distribution

The Dynamics of Objects in Orbits Resembling That of P/Encke

Abstract The overall orbital evolution of bodies resembling that of P/Encke is studied by numerical integration. Dynamical paths are found that connect orbits of this type to their possible sources,
