Atmospheric entry and fragmentation of small asteroid 2024 BX1: Bolide trajectory, orbit, dynamics, light curve, and spectrum
P. Spurny, J. Borovicka, L. Shrbeny +2
Asteroid 2024 BX1 was the eighth asteroid that was discovered shortly before colliding with the Earth. The associated bolide was recorded by dedicated instruments of the European F…
On the Proposed Interstellar Origin of the USG 20140108 Fireball
Peter G. Brown, Jiří Borovička
A critical review of the evidence for the interstellar origin for the USG 20140108 fireball is presented. Examining USG fireball velocities where independent data are available sho…
Oxygen line in fireball spectra and its application to satellite observations
V. Vojáček, J. Borovička, P. Spurný
Aims. Lightning mapper sensors on board weather satellites can be successfully used to observe fireballs. These sensors use a very narrow spectral band at 777nm, which is only a sm…
Data on 824 fireballs observed by the digital cameras of the European Fireball Network in 2017-2018. II. Analysis of orbital and physical properties of centimeter-sized meteoroids
J. Borovicka, P. Spurny, L. Shrbeny
Meteoroids impacting the Earth on a daily basis are fragments of asteroids and comets. By studying fireballs produced during their disintegration in the atmosphere, we can gain inf…
Data on 824 fireballs observed by the digital cameras of the European Fireball Network in 2017-2018. I. Description of the network, data reduction procedures, and the catalog
J. Borovicka, P. Spurny, L. Shrbeny +10
A catalog of 824 fireballs (bright meteors), observed by a dedicated network of all-sky digital photographic cameras in central Europe in the years 2017-2018 is presented. The stat…
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,…
Trajectory and orbit of the unique carbonaceous meteorite Flensburg
Jiří Borovička, Felix Bettonvil, Gerd Baumgarten +4
The C1-ungrouped carbonaceous chondrite Flensburg fell in Germany on September 12, 2019, in the daytime. We determined the atmospheric trajectory, velocity, and heliocentric orbit…
Satellite observation of the dust trail of a major bolide event over the Bering Sea on December 18, 2018
J. Borovicka, M. Setvak, H. Roesli +1
One of the most energetic bolide events in recent decades was detected by the US Government sensors (USGS) over remote areas of the Bering Sea on December 18, 2018, 23:48 UT. No gr…
Two Strengths of Ordinary Chondritic Meteoroids as Derived from their Atmospheric Fragmentation Modeling
Jiří Borovička, Pavel Spurný, Lukáš Shrbený
The internal structure and strength of small asteroids and large meteoroids is poorly known. Observation of bright fireballs in the Earth's atmosphere can prospect meteoroid struct…
Physical properties of Taurid meteoroids of various sizes
Jiri Borovicka, Pavel Spurny
The origin of the Taurid complex is still debated. In addition to comet 2P/Encke, various asteroids were proposed to be members of the complex and thus possible parent bodies of Ta…
The Žďár nad Sázavou meteorite fall: Fireball trajectory, photometry, dynamics, fragmentation, orbit, and meteorite recovery
Pavel Spurný, Jiří Borovička, Lukáš Shrbený
We report a comprehensive analysis of the instrumentally observed meteorite fall Žďár nad Sázavou, which occurred in the Czech Republic on 9 December 2014 at 16:16:45-54 UT. The or…
The Maribo CM2 meteorite fall - survival of weak material at high entry speed
Jiri Borovicka, Olga Popova, Pavel Spurny
High entry speed (> 25 km/s) and low density (< 2500 kg/m3) are two factors that lower the chance of a meteoroid to drop meteorites. The 26 g carbonaceous (CM2) meteorite Maribo re…
Impact detections of temporarily captured natural satellites
David L. Clark, Pavel Spurný, Paul Wiegert +4
Temporarily Captured Orbiters (TCOs) are Near-Earth Objects (NEOs) which make a few orbits of Earth before returning to heliocentric orbits. Only one TCO has been observed to date,…
Are some meteoroids rubble piles?
Jiri Borovicka
The possibility that some meteoroids in the size range 1 - 20 meters are rubble piles i.e. assembles of boulders of various sizes held together only by small van der Waals forces,…
On the age and formation mechanism of the core of the Quadrantid meteoroid stream
Abedin Abedin, Pavel Spurny, Paul Wiegert +3
The Quadrantid meteor shower is among the strongest annual meteor showers, and has drawn the attention of scientists for several decades. The stream is unusual, among others, for s…
Spectral, photometric, and dynamic analysis of eight Draconid meteors
Jiří Borovička, Pavel Koten, Lukáš Shrbený +2
We analyzed spectra, trajectories, orbits, light curves, and decelerations of eight Draconid meteors observed from Northern Italy on October 8, 2011. Meteor morphologies of two of…
Detection of the N2+ First Negative System in a Bright Leonid Fireball
Shinsuke Abe, Noboru Ebizuka, Hajime Yano +2
An ultraviolet-visible spectrum between 300 and 450 nm of a cometary meteoroid that originated from 55P/Tempel-Tuttle was investigated, and its new molecules, induced by atmospheri…
